摘　　要：介绍一种以DSP为控制核心的异步电动机转差频率控制系统在电动游览车中的应用。本系统采用高性能TMS320LF2407DSP控制异步电动机,并产生SVPWM脉宽调制波;实现了电动机的恒转矩起动,恒功率运行的牵引特性。试验结果表明控制系统具有良好的调速性能和较宽的调速范围。A slip frequency control system of asynchronous motor used DSP as control center is presented, which apply to the electric tourist car. The system use super performance TMS320LF2407 DSP to control asynchronous traction motor and generate SVPWM wave, and implement constant torque at start-up and constant power running .The experimentation show the control system has good performance of varying speed and the car speed can vary in large range.
