Decentralized blocking zeros and the decentralized strong stabilization problem
(IEEE, 1995)This paper is concerned with a new system theoretic concept, decentralized blocking zeros, and its applications in the design of decentralized controllers for linear timeinvariant finitedimensional systems. The concept ... 
Decentralized control and periodic feedback
(IEEE, 1994)The decentralized stabilization problem for linear, discretetime, periodically timevarying plants using periodic controllers is considered. The main tool used is the technique of lifting a periodic system to a timeinvariant ... 
Decentralized stabilization of interconnected systems: Structural conditions
(1992)A unified framework is provided for the design of highgain decentralized controllers for the stabilization of several classes of interconnected systems. These classes are characterized in terms of the structure of the ... 
Decentralized stabilization: characterization of all solutions and genericity aspects
(Taylor & Francis, 1992)Electrical and The decentralized stabilization problem of multivariable finitedimensional systems is considered in a fractional setup. A new synthesis procedure for decentralized stabilizing compensators is proposed. The ... 
Decentralized strong stabilization problem
(American Automatic Control Council, 1992)In the decentralized strong stabilization problem for linear timeinvariant finitedimensional systems, the objective is to stabilize a given plant using a stable decentralized controller. A solvability condition for this ...

(IEEE, 1999)LQ optimal repetitive control is developed in singleinput singleoutput discretetime signal/system framework. For a given plant and a stabilizing controller, the LQ optimal repetitive control system can be obtained by ... 
Dynamic boundary control of the timoshenko beam
(Pergamon Press, 1992)We consider a clampedfree Timoshenko beam. To stabilize the beam vibrations, we propose a dynamic boundary control law applied at the free end of the beam. We prove that with the proposed control law, the beam vibrations ...

Evidential logical sensing using multiple sonars for the identification of target primitives in a mobile robot's environment
(IEEE (Institute of Electrical and Electronics Engineers), 1996)Physical models are used to model reflections from target primitives commonly encountered in mobile robot applications. These targets are differentiated by employing a multitransducer pulse/echo system which relies on ... 
Fe promoted NOx storage materials: structural properties and NOx uptake
(American Chemical Society, 2010)Fe promoted NOx storage materials were synthesized in the form of FeOx/BaO/Al2O3 ternary oxides with varying BaO (8 and 20 wt %) and Fe (5 and 10 wt %) contents. Synthesized NOx storage materials were investigated via TEM, ... 
Fixed zeros of decentralized control systems
(IEEE, 2000)This paper considers the notion of decentralized fixed zeros for linear, timeinvariant, finitedimensional systems. For an Nchannel plant that is free of unstable decentralized fixed modes, an unstable decentralized fixed ... 
Global stabilization via local stabilizing actions
(Institute of Electrical and Electronics Engineers, 2006)Stabilization of a linear, timeinvariant system via stabilization of its main diagonal subsytems is the underlying problem in all diagonal dominance techniques for decentralized control. In these techniques as well as all ... 
Local convex directions for Hurwitz stable polynomials
(IEEE, 2002)A new condition for a polynomial p(s) to be a local convex direction for a Hurwitz stable polynomial q(s) is derived. The condition is in terms of polynomials associated with the even and odd parts of p(s) and q(s), and ... 
Local pinning of networks of multiagent systems with transmission and pinning delays
(Institute of Electrical and Electronics Engineers, 2016)We study the stability of networks of multiagent systems with local pinning strategies and two types of time delays, namely the transmission delay in the network and the pinning delay of the controllers. Sufficient ...
