直流电机调速系统 摘要:未来的世界必然是自动化、智能化、网络化、移动化的世界。这一发展趋势导致了一类特殊的计算机系统—嵌入式系统的发展。ARM(Advanced RISC Machines)公司的32位RISC微处理器，以其高速度、低功耗、低成本，功能强大，和特有16/32位双指令集等诸多优异性能，已成为移动通信、手持计算机和多媒体数字消费等嵌入式解决方案中首选的微处理器。 本文介绍了基于嵌入式系统的PWM的直流电机调速系统，选用的微控制器就是SAMSUNG公司的S3C44B0X，并详细讲述了该系统的硬件电路和控制程序设计，以及ADS调试环境和超级终端。 关键词：嵌入式系统；ARM；S3C44B0X；PWM；直流电机 The Principle of Velocity Modulate System for Direct Current Motor of PWM Based on Embedded System Abstract: The future world must be robotized、intellectualized、network realized and mobilized. The tread would boost embedded system, a special type of computer system. ARM (Advanced RISC Machines) is the leading provider of 32-bit embedded RISC microprocessors in mobile, handheld computer and multi-media digital consumption. ARM offers a wide range of processor cores and delivers the high performance together with Low power consumption, low system cost, high performance and specific 16-bit/32-bit double instrument sets. It has been becoming an ideal processor of embedded applications. In this paper, the principle of velocity modulate system for direct current motor of PWM based on embedded system is introduced, The MCU that chooses to use is the S3C44B0X of the company of SAMSUNG，and hardware circuit and control program are also analyzed in detail, as well as the ADS debugging environment and super terminal.
