永磁同步电机自适应高阶滑模Type-2模糊控制

针对t永磁同步电机数学模型不确定问题,提出一种自适应高阶滑模Type-2模糊控制方法.采用积分滑模面二阶滑模控制律,保持传统滑模控制的鲁棒性并实现不含不确定高阶输入输出有限时间稳定;不需要预先确定干扰与不确定上边界,利用yapunov理论获得自适应调节Type-2模糊规则生成Super--Twisting信号削弱抖振.仿真结果表明永磁同步电机具有良好的跟踪性能,同时验证了该方法的可行和有效性.

Adaptive Higher Order Sliding Mode Fuzzy Type-2 Control for Permanent Magnet Synchronous Motor

Aiming at the uncertain for permanent magnet synchronous motor, a control strategy named as higher order sliding mode fuzzy type-2 control is presented. Using integral second order sliding mode, the controller leads to achieve finite time stabilization of the higher order input output without uncertainties and the robustness is ensured. Fuzzy type-2 systems adjusted on-line by adaptation laws deduced from the stability analysis in Lyapunov sense have been introduced to generate the two Super-Twisting signals to avoid both the chattering anti the constraint on the knowledge of upper bounds of both disturbances and uncertainties. Tim simulz, tion results show the good tracking performances and verify the feasibility and effectiveness of the proposed strategy.
