Application of pole-zero concepts to design of sampled-data systems

This paper relates the pole-zero configuration of an error-sampled control system to the transient and steady-state response in a form amenable to straightforward synthesis procedures. The approximate transient response, as defined by percent overshoot and rise time, is specified for a generalized quadratic model in terms of readily discernable parameters. The steady-state error coefficients are developed in terms of the closed-loop poles and zeros. Several examples are used to illustrate the procedure and indicate certain practical conclusions.
