摘　　要：永磁外转子提升机直接转矩控制系统通过砰-砰调节器,对提升机的电磁转矩和电机的定子磁链信号最大值实行调节,但具有极大的磁链脉动以及扭矩波动,低速性能不好。因此选择滑模控制算法对永磁外转子提升机控制系统加以调整优化,利用滑模速度调节器取代了常规PI调节器。实验模拟结果证明:滑模控制算法大幅提升了常规矢量控制系统的调节特性,并降低了扭矩脉动,同时滑模速度调节器也比常规PI调节器拥有更好的负载抗扰能力和健壮性。利用Super-twisting二阶滑模调节器取代了常规砰-砰调节器,仿真结果证明:采用了Super-twisting二阶滑模控制算法的直接转矩调节器,不但能够解决常规一阶滑模结构带来的抖振现象,还明显降低了定子磁链的脉动以及扭矩波动,而且具备了更高的速度追踪能力,对负载扰动和参数改变等不确定性问题有了很大的健壮性。The direct torque control system of permanent magnet external rotor hoist adopts two Bangbang controllers to control the torque and flux amplitude respectively, which has large flux and torque pulsation and poor low-speed performance. The sliding mode control algorithm was used to improve and optimize the control system of permanent magnet external rotor hoist. The sliding mode speed controller was used to replace the traditional PI controller. The simulation analysis shows that the sliding mode control algorithm greatly improves the control performance of the traditional vector control system, reduces the torque pulsation, and the sliding mode speed controller has better load disturbance resistance and robustness than the traditional PI controller. The Super-twisting second-order sliding mode controller was used to replace the traditional Bang-bang controller, and the simulation analysis showed that the direct torque control system based on the Super-twisting second-order sliding mode control algorithm not only effectively eliminated the buffering problem of the first order sliding mode and significantly reduced the stator flux and torque pulsation, but also had strong speed tracking capability and strong robustness to uncertainties such as load disturbances and parameter changes.
