The paper provides survey of some recent robust stability conditions, their mutual comparison, and presents new robust stability conditions for continuous-and discrete-time systems with convex polytopic uncertainty. Robust stability analysis is based on LMI conditions and parameter-dependent Lyapunov functions. The developed stability conditions are(More)
Kybernetika is a bimonthly international journal dedicated for rapid publication of high-quality, peer-reviewed research articles in fields covered by its title. An original Nyquist-based frequency domain robust decentralized controller (DC) design technique for robust stability and guaranteed nominal performance is proposed, applicable for continuous-time(More)
The paper presents an original frequency domain approach to decentralized controller design for specified performance The novelty of the proposed approach consists in assessing the influence of interactions by means of characteristic functions/loci of the plant interaction matrix, and further using them to modify mathematical models of subsystems thus(More)
The paper deals with the design of a discrete-time state space compensator to track a reference command. This approach called Command Generator Tracker (CGT) covers a broad class of reference signals that can be described by a linear differential equation with constant coefficients. The design technique is LQ-based and its principle consists in extending(More)
