Abstract

In this paper, we will study the problem of disturbance attenuation by output feedback for linear systems subject to actuator saturation. Both continuous and discrete-time systems are considered. A nonlinear output feedback, expressed in the form of a quasi-linear parameter-varying system, is constructed that minimizes the the effect of the disturbance on the output of the system. The level of disturbance attenuation is measured in terms of the regional ℒ₂ gain and ℓ₂ to ℓ_∞ gain over a class of energy-bounded disturbances.
