| 摘 要： | 针对永磁同步电机(PMSM)运行过程中内部参数变化和外部负载扰动影响控制性能的问题,采用基于分数阶滑模观测器的PMSM分数阶积分滑模控制(FOISMC)策略。基于FOISMC技术,设计基于新型趋近律的分数阶积分滑模转速调节器,给出能保证系统全局鲁棒性的全程积分滑模面设计方法。基于分数阶理论和滑模控制理论构造分数阶滑模观测器,以实现对速度和转子位置角的高精度估计。仿真实验验证了所提方法的可行性和有效性。

| Abstract: | Aim at the problem of internal parameters variation and external load disturbance affecting the high-performance motor control,a fractional order integral sliding mode control(FOISMC)strategy is developed for PMSM drive system with fractional order sliding mode observer(FOSMO). Based on FOISMC technology,a fractional order integral sliding mode speed regulator based on the new reaching law is designed.And a global integral sliding mode surface design method is presented,which can guarantee the global robustness of the system. Combining fractional order theory and sliding mode control theory,the FOSMO is constructed to achieve high accuracy estimation of the speed and rotor position. Simulation resulas validate the feasibility and effectiveness of the proposed scheme. |
