Abstract
This paper introduces an mathcal H infty state feedback controller for uncertain linear systems with quantizedinput saturation and external disturbances The proposed controller comprises two parts a linear control part to achieve an mathcal H infty performance against model uncertainties and the mismatched part of the disturbances and a nonlinear control part to eliminate the effect of input quantization and the matched part of the disturbances which provides the better disturbance attenuation performance than a controller that deals with a unified disturbance regardless of the presence of matched and mismatched parts Simulation results confirm the effectiveness of the proposed controller
