C07 1. A close-loop control system is given as following: R(s) E(s) E*(s) T=1s S D(z) S S -Ts G(s) (+1) C(₂) C(s) APID control system The transfer function of the analog PID controller is given as D(s) = 1+0.5 +0.4s. The sampling period T = 1s. The input is a unit step signal. (1) Discretize D(s) to D(z) using the first order backward difference method, and figure out the output c(KT). (2) Discretize D(s) to D(z) using the bilinear transform method and to figure out the output c(kT) with the step input.
