| 摘 要： | 怠速控制是发动机电子控制的重要组成部分,其控制效果直接影响发动机的运转稳定性、燃油消耗和排放。本文在某摩托车怠速工况数学模型的基础上,将模糊控制理论应用于小型汽油机怠速稳定性控制中,为减小静态误差,增加了积分控制,构成积分--模糊控制器。在设计中,对控制规则进行了分析。使用Simulink仿真软件对所设计的控制算法进行了仿真研究,结果表明,所设计的控制系统能够很好地满足怠速稳定性控制的要求,是一种较好的控制方法。

| Abstract: | Idle speed control is an important part of Engine Electronic Control System. The control result affects the stability, fuel economy and emission directly. In this paper we'll use a mathematical model of the idle condition, which comes from a motor engine, to control engine idle speed condition. When designing the control system, the fuzzy logic control theory is used. The integral control is added to the controller in order to reduce the static error. The control rule is also analyzed in the design process. The Simulink simulation software is used to study the control algorithm designed. The simulation result indicates that this control system can meet the stability requirement of idle speed control well. The algorithm designed in this paper is an excellent control method. |
