Research on Asynchronous Motor Direct Torque Control System Based on Sliding Mode Variable Structure

  • 摘要: 针对异步电机传统直接转矩控制系统转矩脉动过大,及电机参数变化和负载波动等因素使调速性能变差的问题,提出了用滑模变结构速度调节器代替传统的PI速度调节器,并根据异步电机在同步静止坐标系下的数学模型和滑模变结构理论设计了一种基于转矩误差和磁链误差的滑模控制器,利用获得的参考电压矢量,通过空间电压矢量调制得到逆变器开关控制信号。MATLAB仿真验证了该控制策略能有效减小转矩脉动和磁链脉动,在保证逆变器开关频率恒定的同时,对系统参数摄动和外部干扰表现出较强的鲁棒性。
