The PWM Rectification System Based on Intelligent PI Controller

Abstract:

PWM rectification system with fixed parameter PI can not meet the situation of mutational load and changing from energy feedback status to controlled rectification status. In the PWM rectification system traditionally basing on voltage oriented vector control, traditional voltage loop PI controller was replaced by PI adaptive controller with combination of single neuron and expert system. It is a good solution to the problem. In this paper a simulation model of controlled rectification system in the platform of Matlab/Simulink was established. It appled the S function and get the PI regulation with combination of single neuron and expert system. At last, the paper get the comparison of the simulation results before and after the improvement when load changed and status transformed. The results showed that system of the PI adaptive controller has the faster reaction speed and better robustness. It verified the validity and feasibility of the method.
