Solving for part (b) and (c)

Consider a digital controller for a spin-coating system in which a platter spins with a constant speed and the has a time between readings of T. This may be modeled as: Determine G(z) [please state your assumptions (e.g. ZOH)] For T = 1 ms, a proportional controller (D(z) = K), what is the open loop transfer function? What is the closed-loop transfer function?

Solution

C.closedloop transferfunction forsecondordersysytem is represented by

G(S)/1+G(S) H(S)
