• Course Outcomes: Upon successful completion of the course, students should be able to:

  • Derive discrete-time mathematical models in both time domain (difference equations, state equations) and z-domain (transfer function using z-transform).
  • Apply sampling and reconstruction processes to signals and systems.
  • Understand implications of and tradeoffs among specific choices of transform methods in discretization of continuous filters (controllers).
  • Predict and analyze transient and steady-state responses and stability and sensitivity of both open-loop and closed-loop linear, time-invariant, discrete-time control systems.
  • Design digital controllers to meet both time domain and frequency domain specifications and requirements.
  • Use computer-aided tools such as Matlab/Simulink for digital control system analysis and design.
  • Understand and address issues pertaining to real-time implementation of controllers using microprocessors/microcontrollers.
  • Read a technical paper related to discrete-time control topics covered in the course and implement the described algorithm(s) in Matlab or Simulink code to verify results and use the proposed technique(s).
