摘要
由于模糊自适应PI控制不需要精确的被控对象数学模型,且对于线性系统和非线性系统都具有良好的适用能力,而逐渐应用到电机控制系统中来。但传统模糊自适应PI控制在应用过程中,存在控制性能较差的问题。在模糊自适应PI控制理论基础上,提出一种基于死区时间补偿的永磁同步电机改进型模糊自适应PI控制策略,采用该策略能够实现无论在加速阶段还是减速阶段,均能准确、稳定地调节永磁同步电机转速。
Fuzzy adaptive PI control is gradually applied to motor control system because fuzzy adaptive PI control does not need precise mathematical model of controlled object and it has good practical ability for both linear and nonlinear system.However,tradi⁃tional fuzzy adaptive PI control has a poor performance in application process.To this problem,an advanced fuzzy adaptive PI control strategy for PMSM based on dead⁃time compensation was proposed based on fuzzy adaptive PI control theory.This strategy can be used to regulate the motor speed in the acceleration phase and the deceleration phase accurately and stably.
