基于模糊PI调节器的无刷双馈电机直接转矩控制
Direct Torque Control for Brushless Doubly-Fed Machine Based on Fuzzy-PI Regulator
摘要
Abstract
The inverter switch state was based on the torque error and the stator flux amplitude error in the hysteretic controller which was adopted on the traditional direct torque control for the brushless doubly-fed machine, in this way, current and flux were distorted that results torque ripple in low speed range, even more influents control effect of the whole system. According to this problem, a new direct torque control method with fuzzy-PI regulator for the brushless doubly-fed machine was presented, applying the fuzzy theory to design controller parameters. The simulation results showed that the method was effective to improve the dynamic characteristics of the motor, reduce the torque ripple, improve the speed and the torque control precision,expand the direct torque control system of speed range.关键词
