Abstract

The control problem for a class of a nonlinearsystems that contain the coupling of unmeasured states andunknown parameters is addressed. The system actuation isassumed to suffer from unknown dead zone nonlinearity. Theparameters bounds of the unknown dead zone to beconsidered are unknown. Adaptive sliding mode controller,unmeasured states observer, and unknown parametersestimators are suggested such that global stability is achieved.Simulation for a single link mechanical system with unknowndead zone and friction torque is implemented for proving theefficacy of the suggested scheme
