一种嵌入式智能电子节气门控制系统的实现

Achievement of an Embedded Intelligent Electronic Throttle Control System

根据新型电子节气门的特点,设计了一套基于ARM嵌入式的智能带CAN总线的电子节气门控制系统。采用参数自适应PI的算法,可以智能地调节比例和积分参数,从而改善控制效果。系统带有RS-232串口,能与上位机PC进行通信,并给调试带来很大的方便。调试与实验结果表明该控制系统设计合理、性能稳定、可靠性高。

According to the characteristics of the novel type of electronic throttle （ET）, an electronic control unit （ECU）, based on ARM and CAN BUS was designed, which made it convenient to build up a distributed control system together with CAN BUS interface, controlling arithmetic is parameter adaptive PI. this system has the RS-232 serial port correspondence to be able to carry on the correspondence with superior machine PC, brings very big convenient to the debugging. High reasonability, good stability, strong anti-jamming and reliability have been demonstrated in the design by the experimental operation of the control device.
