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

In this paper, we consider the problems of semiglobal 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
