The Application of SOPC Technology in the Motor Driving Control of Electric Motor Car

Abstract:

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.
