TL;DR: A simple approach to analyse stability robustness of discrete-time singular systems under structured perturbations is proposed and the developed robustness criteria are then applied to solve robust regional pole-assignment problems of singular systems.

TL;DR: Under assumptions that the nominal linear implicit system is regular, impulse-free, with all its generalized eigenvalues lying inside some specified regions, sufficient conditions are proposed to preserve the assumed properties when structured perturbations are added into the nominal system.
Abstract: In this note, under assumptions that the nominal linear implicit system is regular, impulse-free, with all its generalized eigenvalues lying inside some specified regions, sufficient conditions are proposed to preserve the assumed properties when structured perturbations are added into the nominal system. Explicit bounds on perturbations with different structures are given in terms of the spectral radii of some nonnegative matrices. >

TL;DR: In this paper, the robust stability of linear continuous-time generalized state-space systems with structured perturbations is investigated based on the maximum modulus principle and spectral radius of matrices.
Abstract: The robust stability of linear continuous-time generalized state-space systems with structured perturbations is investigated in this paper. Based on the maximum modulus principle and spectral radius of matrices, a new upper bound of perturbations is obtained to ensure that the perturbed generalized state-space system remains regular, impulse-free, and asymptotically stable. It is shown that this bound is less conservative than the existing one. Furthermore, the computation required in the proposed approach is also simpler.

TL;DR: A simple approach is presented to investigate the robustness of pole-clustering in specified regions for generalized state-space systems with structured uncertainties and the obtained results are less conservative than the existing ones.
Abstract: A simple approach is presented to investigate the robustness of pole-clustering in specified regions for generalized state-space systems with structured uncertainties. The proposed method is computationally simple and the obtained results are less conservative than the existing ones. Furthermore, the present approach can deal with more types of regions than other approaches shown in the literature. >

TL;DR: In this article, a simple approach to synthesizing a proportional and derivative state feedback gain for assigning poles to infinity is developed, and the synthesized gain is applied to determine a doubly coprime matrix fraction description (MFD) of a state-space system and solve related problems.
Abstract: A simple approach to synthesizing a proportional and derivative state feedback gain for assigning poles to infinity is developed. We also apply the synthesized gain to determine a doubly coprime matrix fraction description (MFD) of a state-space system and solve related problems. It is interesting to note that the MFD and the solutions to the related problems could be obtained in an explicit formula by using the synthesized gain.
