PIDA Controller designed by Kitti's Method

This paper presents a new method for designing the PIDA (Proportional-Integral-Derivative-Acceleration) Controller for a third order system. The results from simulations shown that all desired specifications can easily met by changing only one parameter. Comparing of the performances of the closed-loop in continuous-time system from this new simple method called “Kitti's Method” with the design technique proposed by Richard C. Dorf, it shown that not only faster with smaller or no overshoot response can be obtained but also the closed-loop system is robustly stable guaranteed. All merits of Kitti's Method are also being held with incorporated Root Locus Technique in discrete-time control systems design.
