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)
The paper proposes a new frequency domain approach to the design of robust decentralized controllers (DC) for continuous-time systems described by a set of transfer function matrices. To guarantee the nominal stability and the prespecified nominal performance, the recently developed DC design technique (Kozáková and Veselý, 2003) has been applied, adapted(More)
The paper deals with the robust PID controller design for performance for linear MIMO systems with state decentralized structure using output feedback. The proposed design procedure is a straightforward state space extension of the frequency domain Equivalent Subsystems Method (ESM) guaranteeing feasible performance achieved in equivalent subsystems for the(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)
