Abstract :
A two-step predictive controller is studied for the input saturated uncertain Hammerstein model. The first step utilizes an unconstrained linear predictive controller that calculates a desired intermediate variable. The second step deals with nonlinearities by solving nonlinear algebraic equation (group) and desaturation. The polytopic description is applied to explore the exponential stability of the closed-loop system and the domain of attraction is further discussed. The effectiveness of the stability results is validated via a simulation example.
