Abstract: This technical note is devoted to a recently discovered phenomenon that takes place in feedback systems with saturating actuators, proportionalintegral (PI) control, and antiwindup. Namely, in such systems, measurement ...

Abstract: This paper presents tracking strategies for the attitude dynamics of a rigid body that are global on the configuration space SO(3) and semiglobal over the phase space SO(3)×ℝ3. It is well known that global attractivity is ...

Abstract: This paper considers the problem of controlling rotating machinery with actuators and sensors fixed in inertial space. Such a problem arises in control of charging and fusing stages in the xerographic process, drilling and ...
