Learning Outcomes

Upon successful completion, the student will be able to:

  • Select appropriate model structures and noise model structures for a control model.
  • Implement off line and real time system identification algorithms such as least squares, instrumental variable methods and maximum likelihood methods and frequency domain and correlation methods.
  • Describe various controller tuning methods.
  • Map continuous time models to the discrete domain and vice versa.
  • Describe the effect of sampling on control.
  • Implement PID, state space, frequency domain, polynomial and LQR design methods for single input, single output control systems.
  • Design continuous and discrete time deterministic state observers and Kalman filters.
  • Implement selector control to deal with limits.
  • Design a cascade control system.
  • Apply feedforward in a control design.
  • Implement dead time compensation control designs.
