Q2: Consider a continuous model of a system:
5s + 5 G(s) = (s + 2s + 4)
And its discrete-time transfer function obtained with a sampling period T = 0.2 as:
-0.4845 z + 0.598
A discrete-time model matching controller is to be designed. The sampling period is given as T = 0.2. Specifications for the desired closed-loop system are as follows:
- Damping ratio is ζ = 0.7.
- Settling time to be 3s.
- There shouldn't be a steady-state error for a step input.
Construct the causal and internally stable discrete-time model matching controller that makes the closed-loop system satisfy the mentioned specifications. (20 points)
