摘要
针对电液控制液压支架在自动跟机过程中推溜不齐问题,提出基于模糊滑模变结构控制方案。通过建立被控液压系统的数学模型,与定义的切换函数结合,然后进行滑模控制律设计,得到滑模变结构函数。通过Matlab软件验证模糊滑模控制系统的可靠性,由仿真结果可得:该方法在自动跟踪调节液压支架推溜方面,其控制效果得到优化。
In order to solve the problem of following push to slip not neat of hydraulic support electro-hydraulic control in the process of automatic machine,a control scheme based on fuzzy sliding mode variable structure is proposed.The switching function is combined with the established mathematical model of controlled hydraulic system,the sliding mode control law is designed,and sliding mode variable structure function is obtained.The reliability of the fuzzy sliding mode variable structure control system is verified by Matlab.The simulation results show that the control effect of this method is optimized in the aspect of automatic tracking and adjusting the hydraulic support slip.
