Abstract :
Techniques are developed for the digital re-design of a continuous time controller (with associated anti-aliasing filter, sampling device and first order hold element), such that the closed loop response to a given reference signal is in some sense preserved. Signal invariant transformation techniques are exploited. The method is compared to other re-design methods documented earlier in the literature
