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 ... 
A dynamic control law for the wave equation
(Elsevier, 1994)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 ... 
Effect of rf pumping frequency and rf input power on the flux to voltage transfer function of rfSQUIDs
(2007)We present the results on the correlation between the flux to voltage transfer function, Vspp, of the rfSQUID and the rfbias frequency as well as rfbias power. Measurements were performed for different SQUID gradiometer ... 
Exact expression and tight bound on pairwise error probability for performance analysis of turbo codes over Nakagamim fading channels
(IEEE, 2007)This letter presents derivation for an exact and efficient expression on pairwise error probability over fully interleaved Nakagamim fading channels under ideal channel state information at the decoder. As an outcome, ... 
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 ... 
Improving AWE accuracy using multipoint Pade approximation
(IEEE, 1994)A new method is proposed for dominant polezero analysis of large linear circuits containing both lumped and distributed elements. This method is based on a multipoint Pade approximation. It finds a reduced order sdomain ... 
Independent estimation of input and measurement delays for a hybrid vertical springmassdamper via harmonic transfer functions
(IFAC Secretariat, 2015)System identification of rhythmic locomotor systems is challenging due to the timevarying nature of their dynamics. Even though important aspects of these systems can be captured via explicit mechanicsbased models, it ... 
Modeling of subsonic cavity flows by neural networks
(2004)Influencing the behavior of a flow field is a core issue as its improvement can yield significant increase of the efficiency and performance of fluidic systems. On the other hand, the tools of classical control systems ... 
On the boundary control of a flexible robot arm
(Institute of Electrical and Electronics Engineers, 2001)We consider a flexible robot arm modeled as a single flexible link clamped to a rigid body. We assume that the system performs only planar motion. For this system, we pose two control problems; namely, the orientation and ... 
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 ... 
Polezero computation in microwave circuits using multipoint Padé approximation
(Institute of Electrical and Electronics Engineers, 199501)A new method is proposed for dominant pole zero (or poleresidue) analysis of large linear microwave circuits containing both lumped and distributed elements. The method is based on a multipoint Padé approximation. It ... 
Robust LQ control for harmonic reference/disturbance signals
(Institute of Electrical and Electronics Engineers, 2000)Linear Quadratic (LQ) controller design is considered for continuoustime systems with harmonic signals of known frequencies and it is shown that the design is reducible to an interpolation problem. All LQ optimal loops ... 
Robust stabilization of the wave equation against small delays
(Institute of Electrical and Electronics Engineers, 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 ...
