摘　　要：以高压共轨柴油机为对象,计算机网络中的"客户机-服务器"网络模型为参考,分析了怠速工况中的影响因素,设计了一个能够对发动机怠速中各种因素进行"动态PID控制"的策略。利用德国ETAS公司的ASCET软件开发平台实现了怠速的控制策略,借助该公司的ES1000硬件和INTECRIO软件进行了台架参数标定试验。结果表明:该怠速控制策略具备柔性特征,并解决了怠速控制软件中的可重用性和可扩展性问题。Referred the computer network model of Client-Server,on the high pressure common rail diesel engine,various parameters in idle-speed conditions were analyzed to develop a control strategy of dynamic PID for these parameters.The idle-speed control models were successfully established by using the ASCET＇s software development tools of the ETAS corporation,then these control parameters of program were calibrated by experiment using ES1000 hardware and INTECRIO software of ETAS.Experimental results show that this control strategy provides good flexibility,and realize also reuse and extension in idle-speed control software.
