Optimal linear controllers and high computational non-linear controllers are normally applied to control the nonlinear systems. Flatness control method is a control technique for linear systems as well as nonlinear systems by static and dynamic feedback namely as endogenous dynamic feedback. This method takes into account the non-linear behavior of the process while preventing complicated compu...

performing fast and accurate methods for modeling the electrical machines has been the subject of several studies and many authors proposed different procedures to attain this aim. beside the accuracy, the speed of the method is of great concern. on the other hand, the capability of the method to be changed according to the need is another important issue. finite element method provides relativ...

The paper analyzes, in brief, various on-line condition monitoring techniques for rotating electrical machines. The different failure mechanisms of electrical machines and several monitoring techniques are analysed. The advantages, disadvantages and reliability of each technique are underlined. A few of the current state of the art techniques are reviewed by surveying the latest developments in...

Electrical machines are the hearts of many appliances, industrial equipment and systems. In the context of global sustainability, they must fulfill various requirements, not only physically and technologically but also environmentally. Therefore, their design optimization process becomes more and more complex as more engineering disciplines/domains and constraints are involved, such as electrom...

A scheme for the solution of the time dependent Maxwell’s equations on composite overlapping grids is described. The method uses high-order accurate approximations in space and time for Maxwell’s equations written as a second-order vector wave equation. High-order accurate symmetric difference approximations to the generalized Laplace operator are constructed for curvilinear component grids. Th...
