Smith Predictor Based PID Controllers Design with Bode’s Ideal Transfer Function Reference Model for High Order Time Delay Systems

In this study, a Smith predictive control scheme is proposed for high order time delay systems. Here, Bode’s ideal transfer function is used as the reference model and its two adjustable parameters (γ and ω
c
are chosen according to the desired step response. Then, PID control is provided so that the output of the high order time delay model can follow the response of this adjusted reference system. Genetic Algorithm optimization method was used to obtain PID parameters. The contribution of the obtained results to the literature is to show the efficiency of the controller design using the Bode’s ideal transfer function of the fractional order for high order time delay systems.
