Semi-global Exponential Stabilization of Linear Discrete-time Systems Subject to Input Saturation via Linear Feedbacks

In this paper, we show that a linear discrete-time system subject to input saturation is semi-globally exponentially stabilizable via linear state and/or output feedback laws as long as the system in the absence of input saturation is stabilizable and detectable, and has all its poles located inside or on the unit circle. Furthermore, the semi-globally stabilizing feedback laws are explicitly c...

Output regulation for linear systems subject to input saturation

Ali Saberi School of Electrical Engineering and Computer Science Washington State University Pullman, WA 99164-2752 U.S.A. The purpose of this paper is to examine the problem of controlling a linear time-invariant system subject to input saturation in order to have its output track (or reject) a family of reference (or disturbance) signals produced by some external generator. It is shown that a...

Anti-windup Compensator Synthesis for Systems with Saturation Actuators

In this paper we synthesize linear and nonlinear output feedback dynamic compensators for plants with saturating actuators. Our approach is direct in the sense that it accounts for the saturation nonlinearity throughout the design procedure as distinct from traditional design techniques that first obtain a linear controller for the 'unsaturated' plant and then employ controller modification. We...

Output Feedback Control for Continuous - Time Switched Linear Systems Subject to Actuator Saturation ∗

This paper is devoted to output feedback H∞ control problem for continuous-time switched linear systems subject to actuator saturation. Using minimal switching rule, nonlinear output feedbacks, expressed in the form of quasi-linear parameter varying system are designed to satisfy a pre-specified disturbance attenuation level defined by the regional L2 gains over a class of energy-bounded distur...
