Fixed time stable event triggered control of uncertain nonlinear systems under input dead zone and full state constraints

Published: 03 May 2024 Publication History

Abstract

Solve problems such as input dead zones and full state constraints in uncertain nonlinear systems. Firstly, based on backstepping control, neural networks, and symmetric obstacle Lyapunov functions, a basic nonlinear controller was designed and filtered through a command filter. Then, an adaptive trigger controller was designed to compensate for dead zones and suppress interference. To achieve system stability. And ensure that all system states do not violate predefined constraint intervals. In this method, the fixed time stability theory is introduced to ensure the boundedness of all signals in the closed-loop system, as well as the fixed time convergence of tracking errors to bounded compact sets, and to reduce the communication burden of the system. Finally, the effectiveness of the control method was verified through simulation examples.
