A Frequency Domain Design Method For Sampled-Data Compensators

A new approach to the design of a sampled-data compensator in the frequency domain is investigated. The starting point is a continuous-time compensator for the continuous-time system which satisfy specific design criteria. The new design method will graphically show how the discrete-time compensator and the sampling period should be selected so the sampled-data feedback system approximate the continuous-time feedback system as good as possible.
