摘要
将异步电机调速的矢量控制方法与电压空间矢量脉宽调制(SVPWM)技术相结合,构建了以SVPWM信号驱动功率器件的异步电机矢量控制调速系统结构图,并用M atlab软件对该系统建模与仿真。仿真结果表明:该系统不仅具有矢量控制调速系统的优越性能,同时具有减少转矩波动,降低输出电流谐波,提高直流电压利用率等优点。
In this paper, combining the vector control method with voltage SVPWM （ Space Vector Pulse Width Modulation ） technique, the structural drawing of vector control adjustable-speed system of induction motor is developed based on SVPWM signal driving power device. This system is built and simulated by MATLAB software. The simulation resuits indicate that this system not only has the good performance of vector-controlled adjustable-speed system, but also has the advantages of reducing torque fluctuation and output current harmonics and increasing of utilization coefficient of DC voltage.
