Abstract :
An on-line modeling method of the sandwich systems with dead zone is proposed in this paper. In this modeling scheme, the so-called key term separation principle is employed in order to handle the nonsmooth nonlinear part in the system. Then, a Recursive General Identification Algorithm (RGIA) is applied to the estimation of the parameters of the model to describe the characteristic of the sandwich system. In this paper, the convergence of the RGIA will be discussed. Finally, a simulation example based on the proposed method is presented.
