Abstract
This paper introduces servo motor control system design which based on ARM. With the continued refinement of social development, people's life growing demand for high quality, high precision CNC machining technology is more and more attentioned.The requirements of high-precision motor control can not do without the rapid development of optimized development of motor control servo motor to improve the overall level, to speed up the development of NC technology of great significance. This paper introduces the Samsung S3C2440 ARM920T for the kernel development board for embedded systems to realize the servo motor speed control.S3C2440 development board through the analysis of hardware resources, control system hardware and software design, full use of the advantage of ARM chip to achieve high-precision servo motor control.The core of this text is S3C2440 development board,it can divided into three modules: control module (touch screen and six free keys), display module, the control object module.To develop the board's PWM module to control the main functions of the control module programming for the output PWM signal to control the servo motor speed to achieve the purpose, while the display module to be displayed, so that timely adjustments.In addition, the servo motor feedback specific to their own modules to enhance the control precision.In addition, the article also describes the ARM chip control advantages to ARM-based chips in embedded engineering because of its advantage in the production of our life with Chiang Kai-shek is widely used.
