Finite-Time Adaptive Fuzzy Control for Unmodeled Dynamical Systems with Actuator Faults

This article concentrates upon the issue of finite-time tracking control for a category nonlinear systems in pure-feedback form with actuator faults and unmodeled dynamics, where loss effectiveness bias fault are considered. Meanwhile, function approximation method utilizing fuzzy logic dynamic surface approach first-order filter implemented to model unknown terms induced from proposed controller procedure tackle “explosion complexity” classic backstepping method. The use maximal norm weight vector estimation adaptive reduces computation load by systems. Within framework control, fault-tolerant protocol is derived guarantee boundedness all signals error controlled system within finite-time. Simulation studies offered show validity theoretical results protocol.
