摘　　要：针对感应电机在不确定性干扰条件下难以进行稳定控制的问题,基于开关增益自适应技术,提出了一种鲁棒滑模控制与磁场定向控制相结合的感应电机速度控制方法。通过在转速与磁通滑模控制器中引入开关自适应增益和积分器插值,保证了与传统滑模控制算法相同的鲁棒性和动态性能,同时有效抑制了定子电压的抖振现象,且所提控制方法对负载转矩变化及电气参数不确定性敏感度较低。最后,通过仿真和物理实验对所提方法进行了验证,结果表明:所提出的控制方法能够准确、快速地跟踪参考信号,同时具有良好的鲁棒性。To control the induction motor stably under the condition of uncertain disturbances,an induction motor speed control method based on robust sliding mode control and field oriented control was proposed based on switching gain adaptive technology. By introducing the switch adaptive gain and integrator interpolation into the speed and flux sliding mode controller,the same robustness and dynamic performance as the traditional sliding mode control algorithm were guaranteed,and the stator voltage chattering phenomenon was effectively suppressed. Moreover,the proposed control method was insensitive to load torque variation and electrical parameter uncertainty. Finally,the proposed control method was verified by simulation and physical experiments. The results show that the proposed control method can track the reference signal accurately and quickly,and has good robustness.
