Hybrid fuzzy PID controller for buck-boost converter in solar energy-battery systems

We propose a hybrid fuzzy PID control system to prevent overshoot and oscillations in DC-DC buck-boost converter for solar-battery system. We designed and simulated a PID, a Fuzzy logic controller, and a hybrid fuzzy PID control system to stabilize the output voltage of the buck-boost converter. The performance results using dynamic response parameters of these controllers such as rise time, overshoot, peak time, and voltage oscillations are presented. Our results support the validity and advantages of the hybrid method.
