摘要
针对传统直接转矩控制方案中转矩波动问题,提出了一种基于离散空间矢量调制(DSVM)技术的电机直接转矩控制(DTC)的控制系统。该系统采用FPGA作为核心器件,极大地减少了分离元件的使用,具有极大的灵活性、扩展性和通用性,抗干扰能力强。仿真和实验结果证明了所提出的基于DSVM电机直接转矩控制算法能够有效减小转矩脉动。
Direct torque control using the pure integral voltage model for torque observation will cause the fluctuations of torque.An improved direct torque control(DTC) system based on discrete space vector modulation(DSVM) is presented.FPGA is used as the core of the system,it implements the most logic functions.The distinctive advantages of the system are flexible,expandable,stable,simple and compact.The simulation and experimental results show the feasibility of the new method.
