Overview of feedback control of dynamic systems

Before we dive into the solutions manual, let's first review some basic concepts and terminology of feedback control of dynamic systems. A dynamic system is a system that changes its state over time in response to inputs and outputs. A feedback control system is a system that uses feedback to compare its output with a desired reference and adjust its input accordingly. A feedback control system consists of four main components: a plant, a controller, a sensor, and an actuator. The plant is the system to be controlled, such as a robot arm, a rocket, or a furnace. The controller is the device that computes the control input based on the error between the output and the reference. The sensor is the device that measures the output of the plant. The actuator is the device that applies the control input to the plant.

The goal of feedback control is to make the output of the plant follow the reference as closely as possible, despite any disturbances or uncertainties that may affect the plant or the sensor. To achieve this goal, we need to design a controller that can provide stability, tracking, and robustness to the feedback control system. Stability means that the system does not exhibit undesirable behavior such as oscillations, divergence, or chaos. Tracking means that the system can follow any desired reference signal within some acceptable error bounds. Robustness means that the system can tolerate some variations or errors in the plant parameters, sensor measurements, or external disturbances.

To design a controller, we need to have a mathematical model of the plant and its dynamics. A dynamic model is a set of equations that describe how the state and output of the plant change over time in response to inputs. There are different ways to represent dynamic models, such as differential equations, transfer functions, state-space equations, block diagrams, or signal-flow graphs. Depending on the type of model, we can use different methods to analyze and design controllers for feedback control systems.

One way to measure the performance of a feedback control system is to study its dynamic response. Dynamic response is how the output of the system changes over time in response to a specific input or reference signal. There are different types of input or reference signals that are commonly used to test dynamic response, such as step, ramp, parabolic, sinusoidal, or impulse signals. Depending on the type of signal, we can use different metrics to evaluate dynamic response, such as rise time, settling time, peak time, overshoot, steady-state error, or frequency response.

The root-locus design method

One of the methods that we can use to design controllers for feedback control systems is the root-locus design method. The root-locus design method is based on the concept and properties of root locus. Root locus is a graphical technique that shows how the roots of the characteristic equation of a closed-loop system change as a function of a single parameter in the controller. The roots of the characteristic equation are also called poles or eigenvalues of the closed-loop system. The poles determine the stability and dynamic response of the closed-loop system.

To sketch and analyze root locus, we need to know some rules and techniques that are derived from complex analysis and geometry. For example, we need to know how to find asymptotes, breakaway points, intersection points, angles of departure and arrival, and so on. We also need to know how to use MATLAB commands such as rlocus or sgrid to plot root locus and find suitable values for controller parameters.

or natural frequency, or a certain percentage of overshoot or steady-state error. Then, we need to find a value for the controller parameter that can place the poles of the closed-loop system in the desired locations on the root locus. We can use trial and error, graphical methods, or numerical methods to find such a value. We can also use MATLAB commands such as rlocfind or sisotool to help us with this task. The frequency-response design method

Another method that we can use to design controllers for feedback control systems is the frequency-response design method. The frequency-response design method is based on the concept and properties of frequency response. Frequency response is a measure of how the output of a system changes in magnitude and phase as a function of the frequency of a sinusoidal input signal. Frequency response can be represented by Bode diagrams or Nyquist plots. Bode diagrams show how the magnitude and phase of the output change as a function of the logarithm of the frequency. Nyquist plots show how the output vector rotates as a function of the frequency in the complex plane.

To plot and interpret Bode diagrams and Nyquist plots, we need to know some rules and techniques that are derived from complex analysis and algebra. For example, we need to know how to find corner frequencies, asymptotes, slopes, phase margins, gain margins, crossover frequencies, and so on. We also need to know how to use MATLAB commands such as bode or nyquist to plot frequency response and find important values for controller design.

To design controllers using frequency response, we need to have some design specifications and objectives for our feedback control system. For example, we may want our system to have a certain bandwidth, gain margin, phase margin, or crossover frequency. Then, we need to find a value for the controller parameter that can shape the frequency response of the closed-loop system in the desired way. We can use trial and error, graphical methods, or numerical methods to find such a value. We can also use MATLAB commands such as margin or sisotool to help us with this task.

State-space design

Another method that we can use to design controllers for feedback control systems is state-space design. State-space design is based on the concept and advantages of state-space representation. State-space representation is a way of describing dynamic systems using state variables and state equations. State variables are variables that capture all the information about the current state of the system. State equations are equations that describe how the state variables change over time in response to inputs and outputs. State-space representation can provide a more general and compact way of modeling dynamic systems than transfer functions or differential equations.

To obtain state-space models from transfer functions, we need to know some rules and techniques that are derived from linear algebra and differential equations. For example, we need to know how to find controllable canonical form, observable canonical form, diagonal form, Jordan form, and so on. We also need to know how to use MATLAB commands such as tf2ss or ss2tf to convert between transfer functions and state-space models.

To design state feedback and state observers using state-space methods, we need to know some concepts and properties of controllability and observability. Controllability is the ability of an input to move the state of a system from any initial state to any desired final state in a finite time. Observability is the ability of an output to reveal the state of a system at any given time. Controllability and observability can be determined by using some tests based on rank conditions or eigenvalue conditions. We also need to know how to use MATLAB commands such as ctrb or obsv to check controllability and observability of state-space models.

the poles of the closed-loop system in the desired locations on the state-space model. We can use trial and error, graphical methods, or numerical methods to find such a matrix. We can also use MATLAB commands such as place or acker to help us with this task. To design state observers using state-space methods, we need to have some design specifications and objectives for our feedback control system. For example, we may want our observer to have a certain convergence rate or error dynamics. Then, we need to find a matrix for the observer gain that can place the poles of the observer system in the desired locations on the state-space model. We can use trial and error, graphical methods, or numerical methods to find such a matrix. We can also use MATLAB commands such as place or acker to help us with this task. Digital control

Another method that we can use to design controllers for feedback control systems is digital control. Digital control is the application of feedback control using digital computers or microcontrollers. Digital control has many advantages over analog control, such as flexibility, accuracy, reliability, and cost-effectiveness. However, digital control also has some challenges and limitations, such as sampling, quantization, aliasing, delay, and stability.

To discretize continuous-time systems using digital control methods, we need to know some concepts and techniques of sampling theory and z-transforms. Sampling theory is the study of how to convert continuous-time signals into discrete-time signals by taking samples at regular intervals. Z-transforms are mathematical tools that can convert differential equations into difference equations or transfer functions into z-transfer functions. Z-transforms can also help us analyze the stability and performance of discrete-time systems.

To design digital controllers using digital control methods, we need to know some concepts and techniques of digital controller design and implementation. Digital controller design is the process of finding suitable values for controller parameters or coefficients that can achieve the desired closed-loop behavior in discrete-time domain. Digital controller implementation is the process of programming or coding the controller algorithm into a digital computer or microcontroller. There are different methods to design and implement digital controllers, such as direct design method, emulation method, pole-zero mapping method, bilinear transformation method, deadbeat control method, and so on.

To design digital controllers using root locus, frequency response, and state-space methods, we need to know how to apply these methods to discrete-time systems or how to convert discrete-time systems into continuous-time systems. There are different ways to do this, such as inverse z-transforms, inverse bilinear transformations, inverse pole-zero mappings, and so on. We also need to know how to use MATLAB commands such as c2d or d2c to convert between continuous-time and discrete-time models.

Control-system design

select appropriate models and methods, compare and evaluate different design alternatives, and implement and test the final controller. Control-system design can also help us deal with complex and realistic problems that involve multiple inputs and outputs, nonlinearities, uncertainties, constraints, and trade-offs.

To apply control-system design to various case studies, we need to follow some steps and guidelines that are based on engineering principles and practices. For example, we need to define the problem and the system, identify the design specifications and objectives, choose a suitable model and method, design a controller using one or more methods, analyze the performance and robustness of the controller, implement the controller using hardware or software, and test the controller using simulations or experiments. We also need to use MATLAB commands such as lsim or sim to simulate the closed-loop system and its response.

The solutions manual provides comprehensive case studies that illustrate how to apply control-system design to different types of systems and problems. Some of the case studies are: a satellite attitude control system, a magnetic levitation system, a DC motor speed control system, a cruise control system, a flexible beam control system, a ball and beam control system, a temperature control system, a CD player servo system, and a robotic manipulator control system. The solutions manual shows how to use different design methods such as root-locus design, frequency-response design, state-space design, and digital control to design controllers for these case studies. The solutions manual also shows how to use MATLAB commands such as linmod or dlinmod to obtain linearized models of nonlinear systems.
