【摘要】 为增强电磁悬浮系统的抗干扰和负载能力,针对磁悬浮列车悬浮系统中存在的非线性不确定问题,采用模糊逼近与模糊滑模相结合的方法,基于等效控制和切换控制设计了自适应模糊滑模控制器,通过TMS320F2812 DSP实现单点悬浮。仿真与试验结果表明,该控制器不但削弱了滑模控制中固有的抖振,而且具有更强的鲁棒性和快速性,还满足电磁悬浮系统实时控制的要求。更多还原

【Abstract】 To improve the anti-interference and load capacity of electromagnetic suspension system, a method of combination of fuzzy approaching with fuzzy sliding mode is applied, for solution of the non-linear and uncertainty problems existing in the suspension system of maglev vehicle. The adaptive fuzzy sliding mode controller is designed based on equivalent efficiency control and switching control. Single- point suspension is realized through TMS320F2812 DSP. The simulation and test results show that the controller reduces the inherent vibrations in sliding mode control, and it features stronger robustness and rapidity, besides its conformance to the real-time control require- ment of electromagnetic suspension system.更多还原
