It is well known that additional space harmonics in the air-gap magnetomotive force (MMF) distribution of the concentrated non-overlapping windings (CW) cause additional losses in the machine. This is especially so for machines used for traction applications where the machine requires to operate over its rated speed and frequency. In this paper, the authors investigates losses present in an int...

Abstract In the article the problem of control of a linear dynamic system with a square coefficient of quality was introduced. Depending on knowledge we have about the parameters of system, the principles of control of the system under conditions of full and incomplete information as well as the differences in values of coefficients of quality were presented. Potential usage of the above mentio...

This paper deals with a key functionality of the future distribution smart grids namely the automatic post-fault network self-healing. To this end we propose an optimization approach that aims finding the post-fault grid topology that minimizes the amount of unsupplied energy to consumers. The approach extends existing optimization models, developed in the context of losses minimization, for ou...

This paper offers three easy-to-use metaphor-less optimization algorithms proposed by Rao to solve the optimal power flow (OPF) problem. are parameter-less algorithms. As a result, algorithm-specific parameter tuning is not required at all. quality makes these simple use and able various kinds of complex constrained engineering problems. In this paper, main aim OPF problem find values control v...

Recent natural or man-made disasters around the world have provided compelling evidence that transportation system plays a crucial role in the emergency evacuation and have stressed the need for effective evacuation traffic management to maximize the utilization of the transportation system and to minimize fatalities and losses. This paper presents a model reference adaptive control (MRAC) fram...
