Introduction to control system analysis, identification, design and implementation. Laboratory work involves real-time identification and control of a range of electrical and electromechanical systems. Topics covered include:

  • History of Control.
  • Representation of linear dynamics and properties of systems.
  • Time domain specifications of performance.
  • Discrete-time systems and the Z-transform.
  • Closed loop and open loop control. Classical PID controllers.
  • Steady state errors and system type. Stability and robustness.
  • Discrete-time systems and design by emulation.
  • Root locus analysis and design of continuous and discrete systems.
  • Frequency response of continuous and discrete time systems.
  • Nyquist plots and stability margins.
  • Lead-Lag control design.
  • Sensitivity and robustness in the frequency domain.
  • Practical design issues approaches.

Learning Outcomes

Upon completion of this course, students will have the knowledge and skills to

  • Understand the properties of feedback and feed-forward control architecture and specify control architecture for a real world problem.
  • Understand and compute sensitivity and complimentary sensitivity for a feedback system.
  • Compute gain and phase margins, and understand implications for control, calculate the Nyquist conditions for a linear system and understand its implications in terms of robust stability margins, compute band-pass for a linear system and understand its significance in control design.
  • Design Lead-Lag compensators based on frequency data for an open-loop linear system.
  • Understand the state-space paradigm and models, and how to design state feedback controllers to achieve pole-placement.
  • Understand the basic structure of a sampled-data system, including a comprehension of issues such as Nyquist sampling theorem and aliasing as well as structure of Z-transform transfer functions and issues associated with inter-sample ripple, compute discrete-time equivalents of continuous-time plants using zero-order hold, trapezoid integration and pole matching techniques.
  • Understand the importance of performance, robustness and stability in control design.
  • Have a strong intuitive understanding of the link between the ODE representation, the s-domain representation and physical characteristics of the time response of an LTI SISO system.
  • Identify simple systems and dominant response characteristics from time domain step-response data.
  • Work confidently with block diagram representations of control systems.
  • Design PID controllers based on empirical tuning rules.
  • Understand system type and steady state tracking error analysis.
  • Compute stability of linear systems using the Routh array test and use this to generate control design constraints.
  • Sketch Evan's root locus diagrams by hand. Use Evan's root locus techniques is control design for real world systems.
