摘 要:This paper presents an adaptive iterative learning control(AILC) scheme for a class of nonlinear systems with unknown time-varying delays and unknown input dead-zone.A novel nonlinear form of dead-zone nonlinearity is *** assumption of identical initial condition for iterative learning control(ILC) is removed by introducing boundary layer *** uncertainties with time-varying delays are compensated for by using appropriate Lyapunov-Krasovskii functional and Young’s *** basis function neural networks are used to model the time-varying *** hyperbolic tangent function is employed to avoid the problem of *** to the property of hyperbolic tangent function,the system output is proved to converge to a small neighborhood of the desired trajectory by constructing Lyapunov-like composite energy function(CEF) in two cases,while keeping all the closedloop signals ***,a simulation example is presented to verify the effectiveness of the proposed approach.
