This paper presents three criteria for evaluating the motoring operations of switched reluctance motor (SRM) drives for electric vehicles (EVs). They imply motoring torque, copper loss, and torque ripple, respectively. The effects of the turn-off and turn-on angles on these criteria are investigated under hysteresis current control. To fulfill the best motoring operation, consequently, the multiobjective...
The exigencies created by the shortage of energy supplies and the ever-growing air pollution stress the need for an alternative solution to the on-board power generation. The purpose of this paper is to develop a novel switched reluctance wind power generator (SRWPG) system for electric vehicles (EVs), which can convert the wind power into electric power so as to charge a battery or support other...
Different cases of the headlight design has been made for the front-lighting system. The design under pitch control, various obstacle location, control of high and low beam are described. The motion control of the front-lighting system is also discussed. It has found that the stepper motor is preferable than DC motor because of the dynamic performance, cost and the control.
In this paper, inductance of an in-wheel switched reluctance motor (SRM) would be computed by using the MEGA software. MEGA, a computer simulation program that model the electromagnetic devices, solves the low frequency subset of Maxwell's equations using finite element method (FEM). Magnetic field strength would be computed in accordance with the SRM specifications. With different values of current...
Adaptive front lighting system becomes more and more popular today. Not only in combustion engine vehicles, but also in some of those new model electric vehicles. Since the new head lamp control system contains several components including drives and controls. Any error on design may affect the overall performance of the system. The simulation of the auto-levelling control system is very important...
This paper presents an experimental direct driving system with in-wheel switched reluctance motor (SRM) for electrical vehicle (EV). The integrated EV direct driving system includes three main parts: the SRM model, driving circuit and control unit. The proposed 8/6 SRM is a novel motor with high performance; the specified external rotor type fits the requirement of in-wheel EV for saving space. The...
This paper is presented a temperature and humidity instrument based on 1-wire sensors. This instrument has simply construction and cheap cost. The sensor is suitable for the installation on the motor for multi-point temperature sensing. It is highly suitable for motor device monitoring and the associated electronic devices. The related circuit is present to show the easy installation of the sensors.
This paper presents a motor drive circuit that is to provide motion control for DC motor which is designed to connect the computer's series port with the CAN fieldbus. The principles of design and the program flow chat are also introduced. The interfacing to the motor drive system is described. The system shows the control and configuration of the motor drive using H-bridge system and the CAN bus...
This paper presents an idea of building a brain-computer interface (BCI) based control for next generation electric wheelchairs. The aim is to explore the area of research on BCI based control to potentially develop a next generation of electric wheelchair which is able to benefit to paralyzed patients. This EEG interfacing development controls a wheel chair through a skid steering method. The mechanical...
This paper discusses skid steering applied to four wheel drive electric vehicles. In such vehicles, steering is achieved by differentially varying the speeds of the lines of wheels on different sides of the vehicle in order to induce yaw. Skid steer wheeled vehicles require elaborate tire model, so author choose the unite semi-empirical tire model. From this model, longitudinal and lateral tire force...
In this paper, the braking strategy is developed for electric vehicle which includes regenerative braking and anti-lock brake system (ABS). Induction motor is used in EV to regenerate kinetic energy. This paper describes the preliminary research and implementation of a fuzzy logic controller to control wheel slip for ABS. The controller is used to enhance the vehicle stability and safety under highly...
