摘　　要：针对组合趋近律下滑模控制器的输出高频振荡问题,提出了一种基于组合趋近律的模糊滑模控制方案.该方案采用模糊控制器实现指数趋近率参数ξ的自适应调整,利用组合趋近律建立滑模控制器的控制律.仿真结果表明,此方案对于提高系统的稳态性能、削弱控制器的输出抖振有良好的效果.A method of fuzzy-sling mode control based on combined reaching law which is used to weaken the high frequency oscillations of silding mode controller was presented.It implemented the adaptive adjustment of ξ by using fuzzy controller,and established the sliding mode control rule with combined reaching law.The simulation results showed that it is effectiveness in proving the steady state performance of the system and eliminate the chattering of controller s output.
