基于补偿机制的延迟约束非线性系统的动态事件触发控制
Dynamic event-triggered control of delay-constrained nonlinear systems based on compensation mechanism
摘要
Abstract
Considering uncertain nonlinear systems with deferred full-state constraints,a finite-time dynamic event-triggered control strategy is proposed.Firstly,an exponential shifting function is designed to make the initial value of the state that violates the constraint enter the constraint range at a faster speed within a predetermined time,and a nonlinear state transformation function is used to keep all the states of the system within the constraint range.Secondly,the error compensation mechanism is designed to reduce the influence of filter error on the performance of the control system.Thirdly,a new dynamic event-triggered mechanism is constructed to reduce the number of triggers of the controller and save resources.The practical finite-time stability of the closed-loop system is proved by Lyapunov theory.Finally,the effectiveness of the designed control strategy is verified by the comparative simulation of the manipulator system under different event-triggered mechanisms.关键词
