Abstract :
A new control scheme of three-phase voltage source is presented. Based on the conception of fuzzy control, and applying a PI fuzzy control with auto-tuning scaling factors to the voltage loop control of rectifier in order to improve the control accuracy of volts DC. The system transform function is deduced and fuzzy control rule table is also defined. The simulation and experiment results showed that the PI fuzzy control with auto-tuning scaling factors has quick response and good robustness, the influence of the variation of load is reduced
