Along with the development of advanced control system, in order to achieve the goal of low energy consumption, low pollution and high degree of automation, the coordination matching work of the motor driving electric motor car and the car body has a better future. By using GW48 hardware development platform and the SOPC technology of nuclear NiosII in FPGA as the central processing unit, and with the aid of the Avalon the peripheral circuit of the motor driving electric motor car is completely under control. This is a improvement of the classic control of the motor (i.e. based on single chip or DSP motor control). This article introduces the design method of the drive control system for electric motor cars. A function module design is conducted for the hardware part, which includes the PWM module and control module, and the PWM module and the VHDL language program is used to form the interface function module. A overall design discourse is conducted for the the software part, design processes of each function module are expounded in this paper. Finally the experimental results are given and they have been analysed. The experiment proves that the precision of SOPC technology in the application of electric motor drive control is high and the application is reasonable. It may become the trend of the development of the electric motor cars in the future.

Aimed at the demand of reducing the wiring harness and declining cost in the automobile control system, electrical controlling system of automobile power window is designed with PIC18F258 single chip computer of integrated CAN bus as the core. Hardware structure and flow chart of software are presented. Through the processing of sample current, it can be judged whether the automobile window meets a barrier, thus realizing the anti-pinch function of window. Compared to the point-to-point control, the bus control not only reduces the wiring harness and cost, but also makes the control more flexible and fast. The experiment results show this system can operate normally, the advantage of this system are reliable performance, low cost, low power consumption and easy to maintain.

Air Volume

This study discusses various control systems that can keep the room pressure and supply/exhaust airflow rate at constant levels in "other rooms" of a highly airtight containment facility when the supply/exhaust airflow is shut off in one of the rooms for decontamination purposes. This study has shown that the constant air volume control system (CAV) allows hysteresis to occur at small differentials on the performance curve of the static pressure differentials and that this hysteresis can cause wide fluctuations in room pressure. In contrast, the variable air volume, central processing unit (VAV-CPU) control system can maintain both airflow rates and room pressures. Each room pressure was controllable to the set level, with an error of less than ±0.5 mmH2O even during transient distur bances. This control system limited fluctuations in the airflow to and from each room to 5 percent during the transient responses. This control system also allows power savings in the operation of supply/exhaust fans, because of the reduced airflow rate and the static pressure of the fans, and is considered to be an excellent control system.
