This paper considers linear time-invariant decentralized singular systems which are either nonregular or, if they are regular, they have impulsive modes. It derives algebraic necessary and sufficient conditions for making a singular system both regular and impulse-free by decentralized output feedback control laws and decentralized proportional-plus-derivative output feedback control laws. 

Robust impulse control of uncertain singular systems by decentralized output feedback

A perturbation upper bound is derived 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.

LMI Approach to Regularization and Stabilization of Linear Singular Systems: The Discrete-time Case

A new class of regularizing stabilizing controllers are proposed that are the sum of predictive and memoryless state feedbacks and aims to regularizing the singular system while the memorylessState feedback is designed to stabilize the resulting regularized system.

The impulsive decentralized cycle index is shown to characterize generic properties on controllability and observability of the closed-loop system through an individual channel (or an external channel).

On regularizing descriptor systems by output feedback

It is shown that if a certain necessary and sufficient condition is satisfied, then both regularity can be established and impulsive modes can be eliminated by output feedback.

Regularizability of descriptor systems

For feedback control of linear systems in descriptor form it is essential that the closed-loop system be regular; that is, there should not be an infinity of solutions of the closed-loop differential

Regularization of descriptor systems by output feedback

It is shown that under these conditions, proportional and derivative output feedback controls can be constructed such that the closed-loop system is regular and has index at most one, which ensures the solvability of the resulting system of dynamic-algebraic equations.
