摘要
针对电液伺服系统的跟踪控制问题,提出了一种基于模糊自学习的滑模变结构控制方案。在常规的滑模变结构控制中引入模糊自学习方法,在不影响滑模变结构控制鲁棒性的情况下,有效地削弱滑模切换控制所产生的抖振。同时系统具有良好的跟踪性能,并大大提高了电液伺服系统的跟踪精度。仿真结果表明了该方案的有效性。
Alming at the tracking control problem of electro-hydraulic servo system,a design method of shding mode var- iable structure control based on fuzzy self-learning for the electro-hydraulic servo system is presented.The chattering brought by sliding mode switch control ean be effectively minimized by introducing fuzzy self-learning in general sliding mode control,without sacrificing the robustness of sliding mode control.Simultaneously,the goal of tracking control is obtained,and tracking precision of electro-hydraulic servo system is highly enhanced.Simulation result verifies the va- lidity of the proposed approach.
