摘　　要：提出了一种新型的电机控制器硬件结构,该控制器包括基于VME总线的单板计算机和自行开发的FPGA电机控制卡。单板计算机具有高计算精度和运算速度,被用来完成控制算法。在FPGA板上开发了VME总线接口逻辑和两电平空间矢量调制策略,通过从总线上获得电压指令并将其调制为脉冲序列来控制变频器。该系统被成功应用于异步电机的控制。A new controller structure for motor drive system was presented.The proposed controller incorporates a commercial VME bus single-board-computer and a customized FPGA card.The computer is utilized to run control algorithm with high precision and speed.A VME bus slave interface and voltage space vector PWM generation unit has been developed on the FPGA board,enabling it to communicate with the computer board and translate the voltage command into PWM pulses which is passed along to the converter.This controller has been successfully used in an induction motor drive system.
