Design of DC Motor Speed Control System Based on SOPC Technology

Abstract

The paper describes design technology of FPGA and design method of SOPC, and designs DC motor speed control system based on SOPC technology. To be more specific, it includes establishing a Nios II embedded system on FPGA for which PWM, tachometer module and relative driver are customized. It also applies C language programming to actualize PID control algorithm, and conducts simulation on main system module functions.
