Parameter estimation for Non-uniformly Sampled Wiener Systems with Dead-zone Nonlinearities

Abstract In this paper, an identification algorithm for the non-uniformly Wiener systems with dead-zone nonlinearities is proposed. Firstly, a uniform model of the Wiener system is reformulated with the help of the lift technique and a switching function. Then, a least squares based iterative recursive algorithm with variable forgetting factor is presented using the auxiliary model and iterative method. Simulation results indicate the effectiveness of the proposed method.
