摘 要: 设计出一种结合T-S模型与滑模技术的自适应模糊滑模控制器,用于PMSM系统的鲁棒速度跟踪。采用自适应技术对不确定性范数进行估计,全局控制器由T-S模糊局部补偿器与滑模监督控制器构成。该方法能够充分利用模糊逻辑控制和滑模控制的优点,且全局闭环系统的跟踪性能和鲁棒性能得到显著改善。实验结果证明了该方法的有效性和正确性。 An AFSMC(adaptive fuzzy sliding--mode control)controller for PMSM system with parameters variation and load disturbances was designed based on this fuzzy model. The AFSMC scheme can drive the dynamics of PMSM into a designated sliding surface in finite time,and guarantee the property of asymptotical stability. It is also shown that the information of upper bound of modeling errors as well as perturbations will not be required when using the AFSMC controller. The performance of the proposed controller was verified by experimental results on PMSM system.
