针对发动机非稳态工况,建立了非线性模型.设计了滑模控制器和PID控制器分别对节气门开度和点火时刻进行自适应调节.对发动机怠速工况进行仿真的结果表明,发动机转速波动幅值低于6 r/min,表明所建的非线性模型适合于发动机非稳态工况控制.
針對髮動機非穩態工況,建立瞭非線性模型.設計瞭滑模控製器和PID控製器分彆對節氣門開度和點火時刻進行自適應調節.對髮動機怠速工況進行倣真的結果錶明,髮動機轉速波動幅值低于6 r/min,錶明所建的非線性模型適閤于髮動機非穩態工況控製.

A non-linear model is set up for engine transient operating conditions. Both sliding mode control-ler and PID controller are designed to realize adaptive regulation of throttle opening and ignition timing respectively.The results of simulation on engine idling show that the amplitude of engine speed fluctuation is less than 6 r/min,indicating that the non-linear model built is appropriate for the control over the transient operating conditions of en-gine.
