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.

The time-triggered architecture for CAN is analyzed. The implementation issue of time- triggered architecture based on 8052 single-chip processor and CAN controller SJA1000 is designed. The maximum number of transmission messages in basic cycle is given. And the scheduling capability is analyzed. The experiment is based on the automotive engine management, the result proves that using time-triggered architecture can not only manage the message transmission but also improve the bandwidth utilization.
