Course objectives

  • Fundamentals of modeling, analysis and control design for linear dynamic systems. This includes both theoretical and some practical aspects of the topic.
  • Knowledge and skills necessary for modeling, analysis and control design for linear dynamic systems.

Learning outcomes

  • Remember the basic structure of feedback control systems and understand the purpose of its components. Be able to offer some illustrative examples of control systems in engineering fields.
  • Be able to recognize that ordinary differential equations (ODEs) can describe the dynamic behavior of physical systems.
  • Understand the application of Laplace transforms and their role in solving ODEs and obtaining transfer functions.
  • Be able to linearize a nonlinear algebraic and ODEs through the use of Taylor series expansion.
  • Be able to calculate and interpret the time-responses of linear dynamic systems.
  • Understand the concepts of state variables, state differential equations, and output equations. Know how to calculate the transfer function from a state variable model, and vice versa.
  • Be aware of block diagrams and be able to transform them.
  • Be aware of frequency spectrum of continuous-time signals.
  • Understand the powerful concept of frequency response and its role in control system design.
  • Understand the differences between controlling the transient response and the steady-state response of a system.
  • Be aware of key test signals used in controls and of the resulting transient response characteristics of basic linear dynamic systems.
  • Understand the concept of absolute, relative stability, and bounded-input, bounded-output stability of dynamic systems.
  • Know how to apply Routh-Hurwitz stability criteria to determine absolute and parametric stability of linear systems.
  • Understand the Nyquist stability criteria and the role of Nyquist and Bode plots.
  • Be capable of analyzing the relative stability and performance of feedback control system using frequency response methods considering phase and gain margin.
  • Be familiar with time-domain and frequency domain performance specifications.
  • Be able to choose and apply P, PD, PI, and PID controllers to improve the system performance.
  • Recognize the improvements afforded by feedback in reducing system sensitivity to parameter changes, disturbance rejections, and measurement noise attenuation.
