Abstract

With the disadvantages of large time-varying, non-linearity and uncertainty, it is hard to establish a precise mathematical model for the current DC thyristor rectifier equipment load which results in conventional PID control performance degradation. A control strategy based on fuzzy PID advanced control theory is proposed. According to expert control rules decision table to determine the size of control quantity, this strategy possesses flexibility and robustness of fuzzy control, and high accuracy of traditional PID control. Using the ARM+FPGA architecture of the embedded system to achieve control strategy, controlling precision and speed have good improvement compared with the traditional single processor design scheme. By simulating 12 pulse rectification control circuitry in MATLAB-SIMULINK, results show that compared to conventional PID, the fuzzy PID control system has smaller overshoot, faster dynamic response and greater stability. It can realize efficient control of controller objects of large power rectifier electronics equipment which have varied application and changing load. In the industrial control and large current power electric field, this method has wide application prospect.
