Abstract :
A novel adaptive data driven control strategy is proposed for general discrete nonlinear systems. The controller is designed based on the Simultaneous Perturbation Stochastic Approximation (SPSA) method, and is constructed through use of a Function Approximator (FA), which is fixed as a neural network here. In this novel approach, the parametric estimation is designed to be adaptive, which greatly improves the control ability. The proposed control strategy is finally applied to solve nonlinear tracking problems for discrete-time nonlinear systems. The feasibility and effectiveness of the proposed adaptive data driven control strategy is well demonstrated through Simulation comparison tests.
