摘要

This paper adopts a kind of fast SVPWM algorithm which can be applied in the control system of three-phase voltage inverter. Compared with the traditional SVPWM, this calculation method is able to realize simple and fast calculation in the microprocessor. In this paper, through establishing simulation model for control system of per-manent magnet synchronous motor in the MATLAB, the calculation methods of fast SVPWM and traditional SVPWM are compared, and the fast SVPWM algorithm is verified to be feasible and effective.%本文采用一种快速SVPWM算法，可应用于三相电压型逆变器的控制系统中，相比于常规SVPWM，该算法在微处理器上实现简单，运算速度快。本文通过在MATLAB中搭建永磁同步电机控制系统仿真模型，对比了快速SVPWM和常规SVPWM两种算法，验证了快速SVPWM算法的可行性和有效性。
