  • You know how to simulate the time responses of a digital system using MATLAB/Simulink and/or Maple and is able to identify the steady-state and transient response. 
  • You are able to find the steady-state and transient responses of a digital system via the z-plane and using the initial and final value theorems
  • You are able to determine the stability of a digital controlled system in the discrete-time domain, in the z-plane and in the s-plane using the bilinear z-transform
  • You know how to design a digital controller via Root Locus in the z-plane and to choose an appropriate sampling interval using the guideline developed by Astrom and Wittenmark
  • You are able to design a digital controller from a given analogue prototype by discretizing it using various methods: Euler approximation, Tustin approximation (bilinear z-transform) and matched poles and zeros
  • You know the influence of the choice of the sampling interval on the performance of a digital controlled analogue process by comparison analog and various digitized PID controllers
  • You are able to design various digital cascade controllers such as dead-beat, Kalman en Dahlin controllers for analogue processes with and without transport delay
