摘要
永磁同步电机是一个多变量、非线性、强耦合的系统,采用传统的控制方法,容易受电机参数变化和负载扰动等不确定因素的影响,难以取得令人满意的控制效果。该文提出一种变论域自适应模糊PID复合控制策略,采用变论域模糊控制实现控制参数自整定和控制规则的自调整,并将其应用到基于矢量控制的永磁同步电机伺服系统速度环中。结果表明,该方法具有动态响应快、抗干扰能力和鲁棒性强等优点。
Permanent magnet synchronous motor is a multi-variable, nonlinear, strong coupling system; the traditional control method is vulnerable to uncertain factors such as the motor parameters change and load disturbance, which is difficult to obtain satisfactory control effect. This paper puts forward an adaptive variable universe fuzzy PID compound control strategy, control parameters is realized by using fuzzy control and variable region since the setting and control rules of self-adjustment. Applying it to the vector control of permanent magnet synchronous motor servo system based on the speed loop, the results show that the method has fast dynamic response, strong anti-interference ability and robustness, etc.
