介绍了一种基于ARM的智能阀门定位系统的硬件设计和定位控制方法。其中应用Philips公司的带CAN总线接口的ARM控制器作为系统的控制核心，既满足了现场实时数据的采集、计算和处理，又可以通过CAN总线使得阀门控制器和控制中心保持实时通信；控制策略采用带智能积分的自学习模糊控制算法，提高了系统的定位精度和智能化水平。

This paper introduces the hardware design and the position control method of a valve positioner based on ARM microcontroller. On the one hand, the selection of ARM with CAN interface of Philips as the core controller can not only satisfy the calculation and collection of real-time data, but also keep a real-time communication between the valve controller and the host computer. On the other hand, the design of control method with intelligent integral and self-learning fuzzy controller improves the intelligent level and the position precision of this valve.
