Abstract

The article considers the control issue for discrete-time nonlinear systems (DNSs). Firstly, when nonlinear functions existing in DNSs are known, a control policy is obtained. Subsequently, when nonlinear functions existing in DNSs are unknown, an adaptive neural controller can ensure that the system states are bounded. Especially, when the controller is designed, for the first time, dynamic surface control (DSC) will be exploited to handle ‘explosion of complexity’ problem of DNSs and a novel first-order discrete-time filter is obtained. Finally, the utilizability of the obtained policy is proved by the simulation.
