Study on A Novel Fuzzy PLL and Its Application

This paper introduces a kind of novel Fuzzy Phase Locked Loop(PLL) controller for induction heating power supply control.A novel PLL is designed with fuzzy control technology, which using fuzzy controller replace the traditional low-pass filter (LPF) to improves the control accuracy and response time. For more, the fuzzy-controlled PLL controller for induction heating supply system have been analyzed. A complete simulation model of the induction heating control system is obtained by MATLAB/SIMULINK software. The simulation results shows the effectiveness and superiority of this novel PLL control system.
