摘要
汽油机采用电子调速器 ,减小瞬时调速率值成为全面提高汽油机调速性能的关键。PID自适应控制按汽油机过渡过程各阶级转速变化的情况 ,确定PID各项的系数 ,调节节气门开度的变化量。试验结果表明 ,瞬时调速率达到 5 .4% ,稳定时间 1 .5 4s,该方法对改善电子调速器的动态特性有明显效果。
For the purpose of dynamic characteristic improvement of the electronic speed regulator,by means of PID adaptive control,the adjustmen t of throttle was governed by speed changes of the gasoline engine at different phases in the transition period.Test results showed that instantaneous speed dro op can reach 5.4%,stabilization time is 1.54s,and the method has an obvious effe ct on improving performance of speed regulating for gasoline engine.
