Robust impulse control of uncertain singular systems by decentralized output feedback

Abstract

This correspondence considers a problem of robust impulse control of uncertain singular systems by decentralized output-feedback. It derives a perturbation upper bound that ensures the existence of decentralized output-feedback control law such that the closed-loop system remains both regularity and impulse free for any allowable perturbations. Algebraic sufficient conditions are also presented that guarantee the existence of so-called decentralized robust impulse controllers.
