摘要
在同步旋转坐标系下,建立了直线感应电动机的矢量控制数学模型。根据矢量控制直线感应电动机的数学模型,提出了一种基于多模糊控制器控制的直线感应电动机矢量控制新方法。1个模糊控制器作为速度控制器,另外2个模糊控制器分别作为电磁推力控制器和磁链控制器。在此控制系统中,采用了电流控制PWM电压源逆变器环节。仿真试验结果表明此种控制方法比基于PID调节器控制的交流传动系统具有更好的控制效果。
The vector control mathematical model of linear induction motor is established under the synchronization reference frame. A new method of vector control, based on multi fuzzy controllers, is given for linear induction motor. One of the fuzzy controllers functions as speed controller, while the other two function as magnetic thrust controller and magnetic flux controller respectively. The PWM voltage source inverter by current control is used in this system. Simulation and experiments indicate that the control method features better control effect than the AC drive system based on PID adjustor control.
