Abstract: The paper deals with the description of a computational model of an ATV vehicle in Simulink software. This computational model is created using the basic elements of own library and represents the main driveline parts for the simulation of longitudinal and lateral vehicle dynamics. The article describes the design and function of the computational model and demonstrates the usage of an ATV model in the NI VeriStand software. It can be simulated on the hardware for real-time testing. A simulation of drive is then done to verify the functionality of the assembled model.

Abstract: Research thermal overload protection not only to protect the motor winding insulation damage due to temperature is too high, also can give full play to the overload capacity of the motor. This paper proposed overload protection model based on heat effects, and deduces the motor internal discrete recursive algorithm of temperature-rise calculation. Based on this algorithm, we constructed the motor internal temperature-rise model, which can calculate temperature-rise of the motor in real-time, and realized the intelligent control of the motor.

Abstract: The speed control system of DC motor normally uses increasing of electric current and voltage for obtaining required speed and torque with regardless of effects from variable of load torque to system. Including that noise will make some errors in speed and torque control. This research aims to present a method for developing the high accuracy in speed control of DC motor by a technique of adaptive torque compensation that is evolved on Lyapunov stability and using Kalman filter for screening out the evident noises in the system. Results reveals that the adaptive torque compensator evolved from the Lyapunov stability can compensate a stable torque and when it is worked with Kalman filter, it can compensate torque correctly and can control more accuracy of motor speed.

Abstract: The intelligent control system of electric tracking trolley that uses infrared sensor as sensitive component and AT89S51 microcontroller as control core is designed in this paper. The design employees infrared receiver and transmitter to detect the runway information and AT89S51 to control the electric trolley tracking and auto parking. The system has the characters of simple circuit structure, high reliability, high intelligence and low power consumption. The paper describes the system's hardware and software design flow in detail. The result shows that the smart trolley in the absence of human intervention could independently run and stably track the target.

Abstract: This study proposes a Mahalanobis Distance Measurement (MDM) method to analyze current waveform for determining the motor’s quality types. The MDM method consists of three major stages: (i) the preprocessing stage which is for enlarging motor current waveforms’ amplitude and eliminating noises, and includes signal amplitude amplifier, filter circuit (eliminating noises), and analog-to-digital converter (ADC) parts, (ii) the qualitative features stage which is for qualitative feature selection on motor current waveforms, and (iii) the classification stage which is for determining motor quality types using the MDM method. It can recognize defective motors and their defective types in less than 0.5 second. In the experiment, the total classification accuracy (TCA) was approximately 99.03% in average. The proposed method has the advantages of good detection results, no complex mathematic computations, hi-speed, and hi-reliability.

Abstract: This paper proposed an artificial neural network (ANN) based space vector pulse width modulation (SVPWM) for motor drive which fully covers the undermodulation and overmodulation regions. A neural network has the advantage of very fast implementation of an SVPWM algorithm that can increase the converter switching frequency, particularly when a dedicated application-specific integrated circuit chip is used in the modulator. Finally, in the environment of MATLAB/Simulink with the Neural Network Toolbox builds the simulation model of system with proposed ANN-SVPWM controller. The simulation results show that the performances of the motor drive with artificial-neural-network-based SVPWM are excellent.

Abstract: Various kinds of household appliances have been widely deployed in the low-voltage grid. They inject conducted noise into the power line system, which may cause a detrimental effect on the Power-line Communications (PLC) channel. This paper examines a new measurement method of conducted Electromagnetic Interference (EMI) on the PLC channel. The proposed method is to facilitate the noise characteristic research, which overcomes the potential difficulties when the measurement is performed according to CISPR 16-2-1. In particular, taking the hairdryer as an example, the conducted noises when the motor is deemed as the noise source are measured by employing the presented method. Moreover, this paper also analyzes the conducted noise of the hairdryer both in the time domain and in the frequency domain, and interprets the noise generating mechanisms with the working principle of the motor in detail. The central issue in all these studies is to research the conducted electromagnetic noise characteristics on the PLC channel.

Abstract: This paper is to review the research trend of Hybrid Electronic Vehicle (HEV) and present a novel design of a HEV based on programmable logic controller (PLC).Since a hybrid vehicle can be at one of five status: Pure Electric Drive, Pure Engine Drive, Parallel Drive, Engine Drive and Electric Power Generation, and Brake for Energy Feedback, this paper presents a design of a HEV controlled by PLC which is to optimize the energy flow according to the vehicle status and the AC permanent magnet synchronous motor. This research is based on anovel design on the transmission system including dual-clutch, transmission control box and planet-gear structure. Switching between the five statuses is automatically controlled by a PLC using the information from the transducers.

Abstract: Motor operates as the power source of the vehicles, which is one of the most important parts in the vehicle system. This paper is going to find out the speed control method of the DC motor of Golf electrical cars from both theory and practice. A virtual instrument, which produces the Pulse Width Modulation (PWM) signal, is developed with LabVIEW to control the motor speed. This smart motor speed controller differs from the traditional mechanical control of DC motor in daily life, and is instructive and significant as a new speed control method of vehicle motor.
