双事件触发下非匹配干扰系统积分滑模抗干扰跟踪控制
Integral sliding mode anti-disturbance tracking control for unmatched disturbance systems under double event triggering
摘要
Abstract
For the dynamic systems with mismatched disturbances,it has an important significance to design anti-disturbance control algorithm with high resource utilization.Under the frame of double event-triggered mechanism,this paper discusses integral sliding mode anti-disturbance control and dynamic performance analysis for the unmatched dis-turbance systems.Firstly,based on the augmented model,the disturbance observer is constructed to realize the dynami-cal estimation of unknown mismatched disturbances.In order to reduce data redundancy and ensure synchronization of transmission,based on the single trigger condition of feedback state and disturbance estimation,a double event-triggered framework is proposed with the principle of first-arrival and same-trigger.Based on this,both the integral sliding surface and the corresponding double event-triggered anti-disturbance controller are designed to guarantee the controlled system convergence to the pre-designed sliding surface.Based on the Lyapunov analysis method,the gains of controller and ob-server are calculated,which ensures the favorable stability and dynamic tracking performance of the augmented system.Further,it is analyzed that the Zeno phenomenon caused by the trigger will not occur.Finally,a typical A4D model is used for the simulation verification,and the simulation results show that the proposed method has satisfactory anti-disturbance performance.关键词
