摘要：
For higher performance speed servo robustness control of brushless DC motor (BLDCM), a novel multiple sliding mode backstepping high order sliding mode nonlinear control approach is proposed. The second order sliding mode Super-Twisting algorithm (STA), which needs no derivative of any variables and eliminates the sliding mode chattering, is used in each step design of the whole backstepping control law. And a self-adaption STA (SSTA) is proposed and used in the virtual control law of the first level subsystem. Compared with the traditional dual closed loop PI control, the proposed method makes the system have higher dynamic and static performance, smaller torque ripple and stronger robustness. Compared with the traditional STA, the proposed SSTA can futher improve the system's robustness for the step load disturbance. Finally, simulation analysis shows the effectiveness of the proposed method. © 2016, Editorial Office of Control and Decision. All right reserved.
