Control Systems/Classical Controls/Print version

Control Systems/Classical Controls Introduction to Control Systems What are control systems? Why do we study them? How do we identify them? The chapters in this section should answer these questions and more. Introduction System Identification Digital and Analog System Metrics System Modeling Classical Controls The classical method of controls involves analysis and manipulation of systems in the complex frequency domain. This domain, entered into by applying the Laplace or Fourier Transforms, is useful in examining the characteristics of the system, and determining the system response. Transforms Transfer Functions Sampled Data Systems System Delays Poles and Zeros System Representation Systems can be represented graphically in a number of ways. Block diagrams and signal-flow diagrams are powerful tools that can be used to manipulate systems, and convert them easily into transfer functions or state-space equations. The chapters in this section will discuss how systems can be described visually, and will also discuss how systems can be interconnected with each other. Gain Block Diagrams Feedback Loops Signal Flow Diagrams Bode Plots Nichols Charts Stability System stability is an important topic, because unstable systems may not perform correctly, and may actually be harmful to people. There are a number of different methods and tools that can be used to determine system stability, depending on whether you are in the state-space, or the complex domain. Stability Routh-Hurwitz Criterion Root Locus Nyquist Criterion Controllers and Compensators There are a number of preexisting devices for use in system control, such as lead and lag compensators, and powerful PID controllers. PID controllers are so powerful that many control engineers may use no other method of system control! The chapters in this section will discuss some of the common types of system compensators and controllers.
