Adaptive control design for nonlinear systems via successive approximations
(American Society of Mechanical Engineers, 2017)The paper presents an approach to the Model Reference Adaptive Control (MRAC) design for nonlinear dynamical systems. A nonlinear reference system is considered such that its response is designed to be stable via Successive ... 
Adaptive robust sampleddata control of a class of systems under structured perturbations
(IEEE, 1993)Robust adaptive sampleddata control of a class of linear systems under structured perturbations is considered. The controller is a timevarying statefeedback law having a fixed structure, containing an adjustable parameter, ... 
Cumulantbased parametric multichannel FIR system identification methods
(Elsevier, 1994)In this paper, “least squares” and recursive methods for simultaneous identification of four nonminimum phase linear, timeinvariant FIR systems are presented. The methods utilize the second and fourthorder cumulants of ... 
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 ... 
Effects of linear filter on stability and performance of humanintheloop model reference adaptive control architectures
(American Society of Mechanical Engineers, 2017)Model reference adaptive control (MRAC) can effectively handle various challenges of the real world control problems including exogenous disturbances, system uncertainties, and degraded modes of operations. In humanintheloop ... 
Experimental study of linear closedloop control of subsonic cavity flow
(2006)A study is presented of the modeling and implementation of different concepts for linear feedback control of a singlemode resonance shallow cavity flow. When a physicsbased linear model is used for cavity pressure ... 
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 ... 
LQ optimal design at finitely many frequencies
(Institute of Electrical and Electronics Engineers, 1998)The notion of Linear Quadratic (LQ) optimality at a single frequency is developed in singleinput singleoutput (SISO) linear timeinvariant (LTI) system/quasistationary signal framework and the optimality condition is ... 
A new method for the computation of all stabilizing controllers of a given order
(Taylor & Francis, 2005)A new method is given for computing the set of all stabilizing controllers of a given order for linear, time invariant, scalar plants. The method is based on a generalized HermiteBiehler theorem and the successive application ...

(2003)A computational method is given for determining the set of all stabilizing proper firstorder controllers for finite dimensional, linear, time invariant, scalar plants. The method is based on a generalized HermiteBie ... 
On the stabilization and stability robustness against small delays of some damped wave equations
(IEEE, 1995)In this note we consider a system which can be modeled by two different onedimensional damped wave equations in a bounded domain, both parameterized by a nonnegative damping constant. We assume that the system is fixed ... 
On the stabilization of a cable with a tip mass
(IEEE, 1994)In this note, we consider a vertical cable which is pinched at the upper end. A mass is attached at the lower end where a control force is also applied. We show that this hybrid system is uniformly stabilized by choosing ...
