2-DOF Smith predictor control system design by root locus technique

Abstract

Smith predictor control is theoretically a good solution to the problem of controlling the time delay systems. However, there are few control design method of Smith predictor scheme for obtain the desired transient and steady state responses arbitrary. In this paper we present a design method of 2-DOF Smith predictor control system design by root locus technique for achieve in the closed loop system performance of stable processes. The simulation results of the control system compared with those using Smith predictor tuned by the Ziegler-Nicholspsila second method and internal model control (IMC) design method will also be demonstrated.
