摘　　要：本文研究了一种基于数字信号处理器(DSP)的电控配气气动发动机控制系统,该控制系统由处理器、曲轴位置传感器、配气机构、功率驱动模块等硬件组成。根据电控气门的进排气控制时序,进行模块化软件设计,搭建电控配气气动发动机系统并进行了相关的实验。实验表明,整体方案可行,配合软硬件设计,可以实现对气动发动机的良好控制。In this paper, a control system based on digital signal processor （DSP） with electro-control variable valve for the air- powered engine is proposed. The hardware of the control system consists of processors, crankshaft position sensor, valve train, power drive module and so on. The software, which is based on EVA＇s timing control for compressed air＇s intake and exhaust, is designed by using modulm＂ programming. Then the experimental platform is set up and the related experiments indicate that the overall project combined with hardware and software is feasible and the system can control the air-powered engine well.
