摘　　要：介绍了以ADMC401DSP芯片为核心的三相交流感应电机SVPWM变频调速系统,具有位置反馈、速度反馈和电流反馈三闭环结构,通过电流反馈及神经元PID控制算法处理偏差数据,减少逆变器输出电流的谐波成分及电动机的谐波损耗,以较低的成本实现三相交流电机连续控制。Taking the DSP chip of ADMC401 as core, the SVPWM frequency-control system for three-phase induction motors equipped with three close ring structure of the position, speed feedback and current feedback was introduced. Through electric current feedback with neuron- PID algorithm punish deviation datum, continuous control of three-phase induction motors with low cost was realized, by means of reduction of harmonic output current in the inverter and harmonic losses in the motor.
