Stable wavelet network adaptive control for nonlinear systems with mismatched uncertainties

The design scheme of the stable adaptive controller, based on wavelet network for a class of the nonlinear system with mismatched uncertainties, was proposed. The uncertain nonlinear function of the system was approximated with wavelet network. The adaptive reduction for the bounds on the network approximation error was considered and there should be no need for prior information of the approximation error bounds. The required prior knowledge is minor. The simulation results have shown that the scheme is feasible.
