Gain Scheduling Implementation in DC/DC Buck Converter using PID Controller
The objective of this paper is to design a Gain scheduling PID control scheme for the DC/DC buck converter to improve the transient performance in different load current conditions. Poor control of the DC/DC buck converter lead to high overshoot and steady state error. And its dynamic response varies with changes in load, especially at high load current conditions. So a Gain scheduling PID control scheme is introduced to overcome this. The proposed control scheme is designed with pole zero cancellation method to adaptively auto tune parameters of the discrete PID controller for efficiently improving the output transient response.
