Abstract
This paper proposes a technique to design the (n-2) stage PD (Proportional-Derivative) controller cascaded with the PID (Proportional-Integral-Derivative) controller in accordance with nth order plants. The Continuous-Time (CT) design is firstly reviewed to show the advantages of the Kitti’s method. The proposed technique is based on the Kitti’s method in combination with the use of First Order Hold (FOH) to discretize the CT plant and Delayed First Order Hold (DFOH) to discretize the CT controller for obtaining the proper Discrete-Time (DT) controller structure. The simulation results confirm that the proposed design technique can be applied to the DT framework with better specifications than it was expected.
