摘　　要：数字式电子调速器应用于汽油机,通过减小瞬时调速率成为全面提高汽油机调速性能的关键。采用PID控制算法,按汽油机过渡过程各阶段转速变化的情况,确定PID各项的系数,调节节气门开度的变化量。实验结果表明,瞬时调速率达到5.4%,稳定时间2.1 s,瞬时调速率和稳定时间都有很大的提高,该方法对改善电子调速器的动态特性有明显的效果。Digital electronic governor is applied to the gasoline, in order to improve the dynamic characteristics of the electronic speed regulator. The PID control algorithm is used to govern the throttle adjustment by speed change of the gasoline engine different phases in the transition period. The test data of engine shows that instantaneous speed droop can reach 5.4%, stabilization time is 2. 1s,and the method has an obvious effect on improving the speed regulating performance of the gasoline engine.
