| Abstract | ||
| A simple control scheme with smith predictor connection is proposed in this paper for time delay higher order systems. The control scheme is simply integral (I) controller with Proportional Derivative(PD)-Sliding mode controller(SMC). The initial values for the P,I, and D parameters are taken from the reduced model of the higher order system. Additional feedback sliding mode control (FSMC) is also used to reduce the effect of uncertainty in the prediction time delay values. A number of examples are tested and compared with other control methods like robust PID controller with smith predictor and Direct synthesis method with smith predictor to illustrate the efficient performance for the proposed control scheme. | ||
