LTI Descriptor Systems Admissibility under Structure Constraints: A Nonsmooth Newton Approach

The paper deals with structured state feedback controllers design for linear time invariant (LTI) singular systems. New necessary and sufficient conditions for the existence of a structured state feedback guaranteeing the descriptor closed loop system admissibility is proposed by dint of linear quadratic (LQ) control theory. These conditions are presented in the form a system of matrix equations i...
