Simulation of submicron pseudomorphic AlGaAs/InGaAs/GaAs high electron mobility transistors
Nadia Lamari, Mohamed Mfitih, Nabil NassifIn this paper, we present the results of submicron pseudomorphic AlGaAs/InGaAs/ GaAs HEMT simulations. Our main interest is the study of electronic temperature behavior in the…
ANN‐based automatic contingency selection for electric power system
K.L. Lo, W.P. Luan, M. Given, M. Bradley, H.B. WanAutomatic contingency selection aims to quickly predict the impact of a set of next contingencies on an electric power system without actually performing a full ac load flow…
Improvement of power systems damping using genetic algorithms aided proportional plus derivative output feedback for TCSC
Y.J. Lin, K.L. LoThis paper develops a proportional plus derivative (PD) control scheme for a thyristor controlled series compensator (TCSC) to reinforce power system damping performance. This PD…

S.X. Chen, T.S. Low, P.B. LeowThis paper reports an application of the combined FEM analysis and Taguchi's DOE method to the parameter optimization of a magnetic recording media. Effects of a soft magnetic…
Time‐energy optimal control of vector controlled induction motor
Hasan Allihalli, Mehmet İlyas BayindirA time‐energy optimal position control algorithm based on the Pontryagin's maximum principle is developed for a vector‐controlled induction motor system. The vector‐controlled…
A new integration algorithm for flux estimation using the voltage model
Hayrettin Can, Erhan Akin, H. Bulent ErtanVector control has very good transient and steady‐state performance in induction motors. Furthermore, most direct stator flux orientation methods do not need speed information and…
Ferroresonance in electrical systems
A.G. MacPhee, S. McKee, R.R.S. SimpsonA series‐LCR circuit is one of the simplest circuits capable of exhibiting ferroresonance. A numerical simulation of such a circuit is constructed using the Preisach model of…
An efficient time discretization procedure for finite element ‐ electronic circuit equation coupling
Patrick Dular, Patrick Kuo‐PengAn efficient and robust time discretization procedure of theta type is proposed in the frame of the finite element‐circuit equation coupling for electronic circuits with switches…
Reducing the complexity order of the algorithms for magnetic field nonlinear problems
Irina Munteanu, Catalin Ciobotaru, Daniel IoanThe numerical solution of electromagnetic field nonlinear problems requires successive building and solving of linear systems of equations. This is the most time–consuming part…
Finite element simulation of a magnetic brake with a soft magnetic solid iron rotor
Herbert De Gersem, Kay HameyerA magnetic brake with a solid iron cylinder rotating at high speeds is considered. The rotor iron is both conductive and permeable. The magnetisation curve is non‐linear. Special…
Recent developments in sensorless and quasi‐sensorless drive
P. Vas, M. Rashed, A.K.M. Joukhadar, C.H. NgThere are two main types of speed/position sensorless closed‐loop variable‐speed electrical drives: sensorless and quasi‐sensorless drives. In sensorless drives, the classical…
