A Control System Based on the Fuzzy Self-Tuning PID Controller for Three-Phase Rectifier
Abstract:
The rectifier implements bidirectional power flow, sinusoidal current and unit power factor control in grid side. This paper describes the design and implementation of the current inner-loop and the voltage outer-loop based on space vector pulse width modulation (SVPWM). A control system based on the fuzzy self-tuning PID for three-phase rectifier is proposed in this paper. The new algorithm based on the fuzzy self-tuning PID can improve the performance of the system. Also, the overshoot of the voltage fluctuation is reduced. Simulation and experimentation results show that the validity of the proposed strategy.
