A robust observer-based model-following control

Moursi, Z. M.; Raptis, J.; Sawan, M. Edwin (IEEE, 1988-06-15)

The model-following problem has been expressed as an LQ-problem, and robustness achieved by including an exponential factor in the cost integrand. In this paper the observer-based case is considered and the inherent ...
Observer based, dead-beat controller with reduced sensitivity

Raptis, J.; Sawan, M. Edwin (IEEE, 1988-06-15)

In this paper, a method is proposed for the design of linear, multivariable, discrete-time controllers with the following characteristics: 1. Constant-gain, minimal order observer - based control laws, 2. n-step, dead beat ...
The Kansas electric utilities research program: a model of utility/university cooperation

Egbert, Robert I; Thomann, Gary C.; Henry, Douglas J.; Loux, R. C. (IEEE, 1989-05-01)
Electric utility experience with solar photovoltaic generation

Jewell, Ward T. (IEEE, 1989-06-01)
Suboptimal model matching problem for two frequency scale transfer functions

Oloomi, Hossein; Sawan, M. Edwin (IEEE, 1989-06-21)

HÂ¿ model matching problem (MMP) for single-input/single-output (SISO) two frequency scale (TFS) systems is considered.
Kalman-Bucy filters with singular correlated noises

Hadiji, M.M.; Sawan, M. Edwin (IEEE, 1989-06-21)

This paper presents a solution to the singular linear minimum-vaviance estimation problem in the discrete time case. An expression for the transfer function of the Kalman-Bucy filter with nonsingular correlated noises is ...
Constrained pole placement using projective controls technique

Fousan, N. S.; Sawan, M. Edwin (IEEE, 1990-05-23)

Projective controls method is used to place the poles of a closed loop system within a circle in the left half plane. The design procedure is noniterative and the solution is obtained via linear quadratic (LQ) design for ...
Pole placement using projective controls and LQ modification

Arar, A. S.; Sawan, M. Edwin (IEEE, 1991-06-26)

A method for solving the output regulator problem by using projective controls was reported by Medanic. Using this method reigenvalues of the state feedback closed-loop system can be retained where r is the number of the ...
Feedback control of nonstandard discrete singularly perturbed system

Beheshti, M. T.; Sawan, M. Edwin (IEEE, 1992-06-24)

Feedback control of linear shift-invariant singularly perturbed discrete systems of the form x1(k+1) = (I+A11)x1(k) + A12)x2(k) + B1u(k), x2(k+1) = A21x1(k) + A22x2(k) + B2u(k), where (I-A22) may be singular is considered. ...
Optimal pole shifting for discrete time systems

Arar, A. S.; Sawan, M. Edwin (IEEE, 1992-06-24)

A recursive method for selecting the state weighting matrix of a linear quadratic regulator problem in order to shift the open loop eigenvalues to be at desired location is presented. This method is capable of shifting a ...
H8 control for singularly perturbed sampled data systems

Vu, T.V.; Sawan, M. Edwin (IEEE, 1993-05-03)
Robustness of sampled-data control to unmodeled high-frequency dynamics

Dinh, Joseph H.; Sawan, M. Edwin (IEEE, 1993-06-02)

Robustness of sampled-data control designs to unmodeled high-frequency dynamics is studied using singular perturbation theory. When a plant is preceded by a zero-order holder, a direct transmission term of the reduced-order ...
Reinforcement and backpropagation training for an optical neural network using self-lensing effects

Cruz-Cabrera, A.A.; Yang, Mingtao; Cui, Guogi; Behrman, Elizabeth C.; Steck, James E.; Skinner, Steven R. (IEEE, 2000-11)

The optical bench training of an optical feedforward neural network, developed by the authors, is presented. The network uses an optical nonlinear material for neuron processing and a trainable applied optical pattern as ...
Improved mathematical model for scheduling single-hop local WDM networks

Best, Patricia K.; Skinner, Steven R. (IEEE, 2003-06-06)
Electrical power systems quality, 2nd edition [Book Review]

Jewell, Ward T. (IEEE, 2003-09-01)
Nonlinear spectrum compression for the hearing impaired via a frequency-domain processing algorithm

Paarmann, Larry D. (IEEE, 2006-08-30)

In this paper, the results of both normal-hearing, and profoundly hearing-impaired adults, tested with spectrum compressed speech via the modified chirp-z algorithm, with and without visual stimuli, are reported. Ten ...
Optimal control for a class of interconnected discrete-time systems with parameter uncertainty

Challoo, R.; Sawan, M. Edwin (IEEE, 2009-03-10)

A large-scale interconnected discrete-time system is considered. This system consists of three interconnected discrete-time subsystems x1, X2, and X3 where x2 and X3 can be directly controlled with the controls u2 and ...
A new method for public involvement in electric transmission line routing

Jewell, Ward T.; Grossardt, Ted; Bailey, Keiron; Gill, Raman (IEEE, 2010-04-19)

Public participation in and acceptance of routing decisions for electric transmission lines has delayed and prevented the construction of numerous lines in recent decades. A new method of public participation called ...
Phase synchronization for distributed sensor networks in feedback bit errors

Wu, Haijie; Ding, Yanwu; Kwon, Hyuck M. (IEEE, 2010-06-25)

It has been reported recently that phase synchronization in distributed sensor networks can be achieved by adjusting the phase in sensors randomly with a single bit feedback from the receiver (base station) to the sensors. ...
