一种改进指数趋近律单向辅助面滑模控制
Improved exponential approach law for sliding mode control with unidirectional auxiliary surfaces
摘要
Abstract
In order to improve the disadvantages of the sliding mode control with unidirectional auxiliary surfaces (UAS-SMC) based on exponential approach law for a class of nonlinear continuous systems,this paper proposed an improved exponential approach law control method.Firstly,according to the nonlinear continuous systems and state constraints,this paper designed the UAS-SMC based on exponential reaching law.Based on this reaching law,it introduced the improved exponential reaching law.Then it proved that the system states would converge to the switching surfaces in a finite time and presented the formula of the convergence time.The simulation results demonstrate that,compared with ordinary UAS-SMC based on the exponential approach law,the UAS-SMC based on the improved exponential approach law controller can more effectively suppress the chattering and has higher convergence speed.关键词
