Title DC Motor Control Circuit Designed Base on the Principle of FPGA
Abstract
Design of control circuit of continuous current dynamo, which based on FPGA（Field－Programmable Gate Array）, manipulates the electrical machine by altering the duty ratio based on the system of PWM（Pulse Width Modulation）, and carries out the clockwise and anti-clockwise rotation， and the start and acceleration of the electrical machine, etc. The thesis proposes theoretical knowledge of continuous current dynamo, PWM speed regulation principle which based on FPGA, Basic knowledge on manipulation of continuous current dynamo and relative hardware written language knowledge of Verilog HDL, thus successfully achieved the logic circuit design and the program writing.
The analysis is based on software simulation and hardware simulation of the design system. The software simulation employs Quartus Ⅱ, and the hardware simulation adopts the downloaded DEA system whose core-board is EP3C25F324C8. By comparison of consequences of software and hardware simulation, the validity of continuous current dynamo that based on FPGA has been verified, after confirming that the system is able to carry out the multiple manipulations such as the clockwise and anti-clockwise rotation， and the start and acceleration of the electrical machine.
