摘　　要：将SVPWM的调制技术应用于异步电机的矢量控制,并且引入SVPWM过调制以及抗积分饱和PI调节算法,以提高了调速系统的动态性能和调速精度。全数字控制利用高速处理器DSP芯片-TMSLF2407A实现了交流调速系统的全数字控制。实验结果充分验证了该设计方案的可行性和正确性。SVPWM is applied in the vector control system of asyachronous motor. Algorithm of over modulation of SVPWM and PI controller without integral saturation is pulled in the speed regulation system for developing both good dynamic performance and high accuracy. At the meantime, high speed processor DSP-TMSLF2407A, is used to realize digital control. The feasibility and correctness of the proposed scheme are demonstrated by experiments.
