Abstract
This paper proposes a successful technique to design a discrete-time (DT) proportional-integral-derivative-acceleration (PIDA) controller for third-order plants. The proposed technique consists of three major steps: discretization of the controlled plant using the first-order hold (FOH) method, discretization of the continuous-time (CT) PIDA controller structure using the delayed first-order hold (DFOH) method to achieve the DT PIDA controller structure, and design of the target controller using the Kitti’s method. Simulation results confirm that the controller designed by utilizing the proposed technique provides equivalent performances compared to a conventional CT controller and a DT controller discretized by utilizing the Tustin’s method.
