Abstrakt: In this paper, the H ∞ model predictive control is investigated for nonlinear discrete stochastic systems with actuator saturation. The actuator saturation , random nonlinearity and external disturbances simultaneously are included in this controlled systems. The saturation function is decomposed into a linear and a nonlinear part by u-sing the sector conditions, and the stochastic nonlinearity is described by statistical means. Based on the Lyapunov stability theorem and linear matrix inequality (LMI) technique, sufficient conditions are given to guarantee the H∞ performance and the stochastic stability of closed-loop system. Finally, a simulation example is employed to show the feasibility and effectiveness of the H∞ model predictive control method. [ABSTRACT FROM AUTHOR]
