Approximations in compensator design: a duality
(The Institution of Engineering and Technology (IET), 2002)In classical controller design, poles fat to the left of dominant poles are sometimes ignored. Similarly, in some proportionalintegral compensation techniques, the controller zero is placed close to the origin and design ... 
An exponential stability result for the wave equation
(Elsevier, 2002)We consider a system described by the onedimensional linear wave equation in a bounded domain with appropriate boundary conditions. To stabilize this system, we propose a dynamic boundary controller applied at the free ... 
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 ... 
A modelbased scheme for anticontrol of some chaotic systems
(World Scientific Publishing, 2003)We consider a modelbased approach for the anticontrol of some continuous time systems. We assume the existence of a chaotic model in an appropriate form. By using a suitable input, we match the dynamics of the controlled ... 
On stabilizing with PID controllers
(IEEE, 200706)In this paper we give an algorithm that determines the set of all stabilizing proportionalintegralderivative (PID) controllers that places the poles of the closed loop system in a desired stability region S. The algorithm ... 
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 flexible beam with a tip mass
(Society for Industrial and Applied Mathematics, 199811)We study the stability of a flexible beam that is clamped at one end and free at the other; a mass is also attached to the free end of the beam. To stabilize this system we apply a boundary control force at the free end ... 
Plant Order Reduction for Controller Design
(IEEE, 200306)Two dual methods of plant order reduction for controller design are proposed for linear, timeinvariant, multiinput multioutput systems. The model reduction methods are tailored towards closedloop stability and performance ... 
Robust antiwindup compensation for highprecision tracking of a piezoelectric nanostage
(Institute of Electrical and Electronics Engineers Inc., 2016)Ultrahighprecision tracking in nanomanipulations poses major challenges for mechanical design as well as servo control, due to the general confliction between the precision requirement and large stroke tracking. The ... 
Robust controller design based on reduced order plants
(Taylor & Francis, 2006)Two dual controller design methods are proposed for linear, timeinvariant, multiinput multioutput systems, where designs based on a reduced order plant robustly stabilizer higher order plants with additional poles or ... 
Robust stabilization of the wave equation against small delays
(IEEE, 1994)In this paper we consider a system which can be modeled by (undamped) wave equation in a bounded domain. We assume that the system is fixed at one end and is controlled by a boundary controller at the other end. We also ... 
Stabilization and disturbance rejection for the wave equation
(Institute of Electrical and Electronics Engineers, 199801)We consider a system described by the onedimensional linear wave equation in a bounded domain with appropriate boundary conditions. To stabilize the system, we propose a dynamic boundary controller applied at the free end ...
