基于事件触发的非线性系统有限时间输出反馈跟踪控制
Event-Triggered Adaptive Finite-Time Output-Feedback Tracking Control for Nonstrict-Feedback MIMO Nonlinear Systems
摘要
Abstract
For non-strict feedback multi-input multi-output nonlinear systems with unknown states,a finite-time tracking control strategy based on event-triggered strategies is proposed.By taking advantage of the approxima-tion characteristics of neural networks for nonlinear functions,a neural network observer is constructed to estimate the unknown state in the system,and dynamic surface control technology is used to avoid the"complexity explosion"problem in traditional backstep control.Unlike the traditional relative threshold event-triggering mechanism,by in-troducing adaptive dynamic variables,not only can the update frequency of the actuator be effectively reduced and communication resources be saved,but also the trigger interval can be dynamically adjusted according to the charac-teristics of the system state.Theoretical analysis proves that the proposed control strategy can eliminate the influ-ence of unknown states and ensure the stability of the closed-loop system.Taking the simulation of the interconnect-ed inverted pendulum system as an example,the finite-time convergence of tracking error was achieved,verifying the effectiveness of the proposed strategy.关键词
