The system proposed in this paper will monitor the speed of vehicles consistently critical zones using GPS facilities. Road-based accidents are quite common nowadays. One vital reasons for mortality rate worldwide is due to various causes such as over speeding, abnormal changes road path like curves and bumps, etc. Because innovations wireless technology, Intelligent Transport System (ITC) has ...

In this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (LIMs). Dynamical equations of LIM have been considered accurate. In other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. Then equations of the reference model and adaptive mode...

This paper presents a simple sliding mode control strategy used for an electronic differential system for electric vehicle with two independent wheel drives. When a vehicle drives along a curved road lane, the speed of the inner wheel has to be different from that of the outer wheel in order to prevent the vehicle from vibrating and travelling an unsteady path. Because each wheel of this electr...

This paper presents a simplified fuzzy logic-based speed control scheme of an interior permanent magnet synchronous motor (IPMSM) above the base speed using a flux-weakening method. In this work, nonlinear expressions of d-axis and q-axis currents of the IPMSM have been derived and subsequently incorporated in the control algorithm for the practical purpose in order to implement fuzzy-based flu...

the goal of this research is the derivation of method for evaluation of efficiency improvement potential for district heating systems with focus on variable speed centrifugal pump. the effectiveness of the usage of the proportional pressure control is compared with the constant pressure control. this is why, energy calculation analyses have been realized for variable speed centrifugal pumps, an...
