Accurate assessment of the electro-magneto-mechanical energy conversion process usually requires a multi-physics Finite Element (FEA) analysis. Since FE analysis is a time consuming numerical process, lumped parameter models, simplified equivalent magnetic circuits, and separated field analysis are usually used for design and control of electric motor and generator drives. This computational burden...
Three-phase ac-ac PWM converters with voltage or current dc-link are employed for electric drives requiring bidirectional power flow and a high input power factor. For more than thirty years matrix converters have been considered to offer significant advantages over the conventional two-stage concepts with dc-link energy storage in terms of power conversion efficiency and volume of passive components...
Estimated worldwide sales for rechargeable batteries, was around US$36 billion in 2008 and this is expected to grow towards US$51 billion by 2013. As per market reports, US demand for primary and secondary batteries will increase by 2.5% annually to 16.8 billion in 2012, while primary batteries will account for 5.8 billion with a growth rate of 3%. The insatiable demand for smaller lightweight portable...
This paper presents a method for loss calculation, including core losses and winding losses, and temperature rise in high frequency transformer design under forced-air convection. Analytical models of winding losses for multiple-layer copper foil and Litz wire windings with MMF boundary conditions have been developed. Geometric parameters of conductor and distribution of magneto-motive forces are...

The Smart Grid (SG) has come to describe a next-generation electrical power system that is typified by the increased use of communications and information technology in the generation, delivery and consumption of electrical energy. The National Institute of Standards and Technology Smart Grid Conceptual model provides a high level framework that defines seven important Smart Grid domains: Bulk Generation,...
The problem of controlling load perturbed induction motors is tackled by means of an observer based robust discrete-time control. In this scheme, model uncertainties and external disturbances are included in a general additive disturbance input which is to be on-line estimated and subsequently rejected via the controller actions. The observer carries out the disturbance estimation, thus reducing the...
This paper provides a nuclear norm minimization approach to an identification of linear systems with finite word-length data. Measurement data sampled from low resolution sensors are sequence of a few bit data and have large quantization errors, which deteriorate the identification accuracy. In this paper, the identification problem is formulated as a rank minimization problem, and the nuclear norm...
This paper discusses the algebraic design via Diophantine equations of dual-rate regulators generalizing the well-known interpolation constraints for the reference model in single-rate systems. The results are applicable to unstable plants. A simulation example on a robotic model is presented.
