In this paper we give a theoretical and a computational solution to the most general inner-outer factorization problem formulated for a discrete-time system G. Our method is based on descriptor state-space computations and relies on an efficient dislocation of the minimal indices and of the “unstable” zeros of G by left multiplication with all-pass factors. The minimal indices are dislocated by solving...
Given an arbitrary rational matrix G, we are interested to construct the class of coprime factorizations of G with J-all pass denominators of McMillan degree as small as possible. Recently, we have given necessary and sufficient solvability conditions and a construction of the class of solutions in the canonical case in which the denominator has McMillan degree equal to the number of unstable poles...
Numerically reliable state space algorithms are proposed for computing coprime factorizations of periodic descriptor systems. Two factorizations are considered for causal periodic descriptor systems: stable coprime factorizations and coprime factorizations with inner denominators. The corre- sponding algorithms are based on a recursive generalized periodic Schur method for eigenvalue assignment. For...
The paper deals with the stability properties of discrete time linear model predictive control systems. The closed loop systems are optimized using different performance criterions in a receding horizon fashion, and then the eigenvalue properties of the closed loop systems are investigated for the different conditions. Performance criterions may be combinations of terms belonging to state, control...
