基于空间电压矢量的交流调速系统研究

Research on AC Speed Regulation System Based on Space Voltage Vector

在异步电动机的变频调速波形采用电压空间矢量法,是从电机的角度出发,着眼于如何使电机获得幅值恒定的圆形磁场。本文在分析了电压空间矢量控制的优越性基础上,设计了交流异步电动机电压空间矢量控制的硬件电路和软件控制程序,并对控制系统进行了MATLAB/SIMULINK仿真,验证了系统的性能。

The voltage space vector method is used in the frequency conversion and speed regulation waveform of asynchronous motor,which is from the perspective of motor,focusing on making the motor obtain a circular magnetic field with constant amplitude.Based on the analysis of the advantages of vsvc,this paper designs the hardware circuit and software control program of vsvc for AC asynchronous motor,and simulates the control system with Matlab/Simulink to verify the performance of the system.
