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 proportional-integral 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 one-dimensional 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, time-invariant, finite-dimensional systems. For an N-channel plant that is free of unstable decentralized fixed modes, an unstable decentralized fixed ... -
A model-based scheme for anticontrol of some chaotic systems
(World Scientific Publishing, 2003)We consider a model-based 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, 2007-06)In this paper we give an algorithm that determines the set of all stabilizing proportional-integral-derivative (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 one-dimensional 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, 1998-11)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, 2003-06)Two dual methods of plant order reduction for controller design are proposed for linear, time-invariant, multi-input multi-output systems. The model reduction methods are tailored towards closed-loop stability and performance ... -
Robust antiwindup compensation for high-precision tracking of a piezoelectric nanostage
(Institute of Electrical and Electronics Engineers Inc., 2016)Ultrahigh-precision 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, time-invariant, multi-input multi-output 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, 1998-01)We consider a system described by the one-dimensional 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 ...
