Abstract

Abstract:

An event-triggered fuzzy adaptive control is proposed for a class of uncertain nonlinear systems with input dead zones. Considering that the function approximation error changes with time，improved fuzzy logic systems（FLSs）are used to solve the uncertain part of the proposed system. In order to save system transmission resources， an event trigger mechanism taking two-bit signal transmission is established. And a designed auxiliary system is introduced into the controller， to compensate for the impact of input dead zones appearing in the practical system. According to the theoretical analysis and simulation results，the proposed system is effective and can guarantees the boundedness of all signals.

Key words: event-triggered control, input dead zone, fuzzy logic system, auxiliary system, two-bit signal transmission, adaptive control
