Control of linear systems with input saturation and matched uncertainty and disturbance

In this paper, we consider the problems of semi- global and global internal stabilization along with disturbance rejection for the case of so-called matched uncertainties and disturbances for linear systems subject to actuator saturation. We develop here low-and-high gain and scheduled low-and-high gain state as well as measurement feedback design methodologies to solve the posed stabilization and disturbance rejection problems.
