摘要/Abstract

摘要： 针对当前电子节气门因复位弹簧而引起的非线性特性问题,结合电子节气门的结构,分析了其变结构非线性特征,采用基于滑模控制的非线性控制方法,给出了该方法的里雅普诺夫稳定性证明。对电子节气门的经典PID(Proportional Integral Derivative)控制、变速PID和滑模控制进行了实验比较。在以16位80C196KC单片机为核心控制器的控制板上试验表明,变速PID在节气门开度从小到大的阶跃变化时，无超调量,在从大到小的阶跃变化时,超调量为4\^8％,而滑模控制在节气门开度从小到大阶跃时，无超调量,从大到小变化时，超调量为1％。滑模控制法对电子节气门的非线性具有较好的控制效果。

Abstract: Precise ETC(Electronic Throttle Control) is critical to powerful torque-based engine management system. Aiming at the problems brought by the non-linearity of the restoration spring of the electrical throttle, combing the the electric throttle structure, its non-linearity is analyzed.The sliding mode control algorithm is adopted and its stability certification is given. Experiment with conventional PID(Proportional Integral Derivative) and sliding mode control is carried out on the electrical throttle using the control board based on 16 bit 80C196KC singlechip. The experiment shows that when variable PID is used, no overshoot exists when the open degree of ECT changing from small degree to large degree, and when its changing from large degree to small degree, the overshot is 48％.Whiling the sliding mode is used no overshoot exists when the open degree of ECT changing from small degree to large degree, when its changing from large degree to small degree, the overshot is 1％,is reduced greatly. The sliding mode control system has a good control result to the non-linearity of ETC.
