Abstract

In this paper, a complete solution for the 1 sampled-data problem is furnished for arbitrary plants. Then 1 sampled-data problem is described as follows: Given a continuous-time plant, with continuous-time performance objectives, design a digital controller that delivers this performance. This problem differs from the s-tandard discrete-time methods in that it takes into consideration the inter-sampling behaviour of the closed loop system. The resulting closed loop system dynamics consists of both continuous-time and discrete-time dynamics and thus such systems are known as “Hybrid” systems. It is shown that given any degree of accuracy, there exists a standard discrete-time 1 problem, which can be determined apriori, such that for any controller that achieves a level of performance for the discrete-time problem, the same controller achieves the same performance within the prescribed level of accuracy if implemented as a sampled-data controller.
