In proportional-Integral (PI) controlled CUK converter, the system is unstable due to the high oscillation caused by excessive integration. A proportional-integral-differential (PID) controlled converter is used to eliminate this instability. In this article, PID design and control of the CUK converter has been implemented. The dynamic model of the system is found from the mathematical analysis of the converter. A fourth order parametric transfer function is obtained here. The converter is simulated in virtual environment by using the obtained parameters. Interface design was carried out to find the control parameters belonging to the system. The control parameters (P, PI and PID) of the system were obtained using the Ziegler-Nichols method. The results were evaluated by simulating the system as uncontrolled, PID controlled and Regulated PID controlled. It has been found that PID control performance is more effective than PI control at different parameter values of CUK converter.
