This paper is concerned with the problem of state feedback control for nonlinear quadratic systemswith randomly occurring actuator saturation. The considered actuator saturation is assumed to occur in a randomway, and the randomly occurring rates of the saturation are time-varying with known upper and lower bounds. Byusing the Lyapunov approach, a sufficient condition is given to guarantee that the closed-loop system is locallyasymptotically stable in mean-square sense. The desired controller gain can be obtained in terms of the solutionsto certain linear matrix inequalities. Finally, a simulation example is provided to show the effectiveness of theproposed control scheme.
