AN OPTIMAL ALGORITHM FOR SAMPLED-DATA ROBUST SERVOMECHANISM CONTROLLER USING EXPONENTIAL HOLD

Abstract

A new structure of sampled-data robust Servomechanism controller using exponential hold is developed. An optimal algorithm is also proposed for choosing the controller parameters of two important special classes. The algorithm is derived by minimizing a square-error performance index, and the solution can be solved from a discrete-time algebraic Riccati equation.
