It was recently presented that the Reluctance Synchronous Motor (RSM) is well suited for variable gear electric as well as for hybrid electric vehicles. This paper deeply investigates the capabilities of a Reluctance Synchronous Motor and proposes a multi parameter estimation scheme for Reluctance Synchronous Motor under variable-speed control. The proposed control evaluation model is fully eff...

Variable acoustic properties can be obtained at the diaphragm of an electroacoustic transducer, with the help of very basic control strategies, among which is the simple electrical shunting of the transducer. These shunt techniques are compared to active feedback techniques for controlling the acoustic impedance of an electroacoustic transducer. It is shown here that the formulation of feedback...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

Nowadays the use of Hybrid Electric Vehicles (HEV) is increasing dramatically. The HEV is mainly dependent on electricity and there is always a need for storage of charge. Fuel Cell (FC), Batteries and Ultra Capacitor are being used for the proposed HEV as an electric power source or as an energy storage unit. The aim of developing an energy management technique is to utilize the sources accord...

objectives: the purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (dec) could accelerate the amount of orthodontic tooth movement (otm) in young adult mixed breed dogs. methods: fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. orthodontic force was applied...

We demonstrated a continuous viewing angle controllable liquid crystal display (LCD) adopting a thermally variable retardation layer (TVRL) using nematic liquid crystal with transparent electric-heating lines to control temperature. The simulated and experimental results of the proposed LCD show continuous and symmetric viewing angle characteristics by tuning the retardation of TVRL using Joule...

PID control algorithm is widely used in servo control system. Because of the non-symmetrical structure of the hydraulic cylinders in the angle position electric-hydraulic servo system of plant converter, the conventional PID control has low control precision and bad flexibility. To solve the problem, an improved digital PID control algorithm with variable sampling periods is proposed. Based on ...

This paper describes the Power System Blockset (PSB) from The MathWorks, Natick, MA, which is a new software package for the simulation of electric circuits, power systems, power electronic devices, and electric drives. The PSB is developed in the graphical Simulink environment of the general-purpose Matlab software. This blockset inherits a number of advantages from its development environment...

Fuzzy control strategy is developed for the dual-clutch single-axis torque coupling parallel hybrid electric vehicle. In this paper the torque distribution fuzzy controller which has been designed for the hybrid vehicle which is optimized by genetic algorithms. The simulation model of the hybrid vehicle was built upon matlab / simulink and ADVISOR software. Then a fuzzy rules and correspondent ...
