Identification and Nonlinear PID Control of Hammerstein Model using Polynomial Structures
نویسندگان
چکیده
In this paper, a new nonlinear discrete-time PID is proposed to control Hammerstein model. This model is composed by a static nonlinearity gain associated to a linear dynamic subsystem. Nonlinear polynomial structures are used to identify and to control this class of systems. The determination of parameters is based on the use of RLS algorithm. A coupled two-tank process is given to illustrate the effectiveness of the proposed approach. Keywords—Parametric identification; Hammerstein model; RLS algorithm; Polynomial structure; Nonlinear PID controller

متن کاملIdentification and Predistortion for a Class of Nonlinear Systems
The identification algorithm of Wiener-Hammerstein nonlinear model is proposed in the paper. When the nonlinearity in the Wiener-Hammerstein model is approximated by polynomial or spline function, the identification algorithms can be implemented iteratively, and the compensator for the nonlinear distortion is given by using the estimated Wiener-Hammerstein model and its inverse. A numerical sim...
