摘　　要：介绍了一种基于空间矢量脉宽调制(SVPWM)的电动游览车异步电机调速控制系统。分析了电动游览车的转差频率控制原理和SVPWM在Matlab/Simulink仿真工具以及DSP数字控制中的实现,并以TMS320F2407控制核心、西门康(SEM IKRON)SKHI22为驱动模块,构成电动游览车的控制系统。仿真和实验结果表明,此控制方法在电动车加减速运行和负载转矩变化时,控制性能良好,运行稳定。A speed control system of electric tourist car was introduced in this paper, which was based on space vector pulse width modulation （SVPWM）. The theory of closed-loop slip frequency control and SVPWM were analyzed and simulated also. The control system was implemented by DSP, which used TI＇s TMS320LF2407A as the control core, and SEMIKRON＇s SKHI22 as the drive module. The results of simulation and experiment showed that, the system had good speed control performance and stability, as speed and loads change of the electric tourist car.
