摘　　要：In order to improve the steady and dynamic characteristic of the idle speed control and study the performance of the fuzzy control method for the idle speed control, a fuzzy control system is developed to control the idle speed of gasoline engine. The construction and working principle of the fuzzy controller are described, and the design procedure of the fuzzy controller is given in detail. The control parameters are determined by computer simulation. The simulation and experiments on the engine test bench show that the idle speed is controlled accurately both in stationary and in dynamic states, and the fuzzy control method is robust to the changes of engine parameters.为了提高怠速转速控制的稳态和动态特性 ,研究模糊控制方法在怠速控制中的性能 ,设计了一种汽油机怠速转速模糊控制系统 .介绍了怠速模糊控制系统的结构和工作原理以及模糊控制器的设计过程 .通过计算机仿真确定了控制系统的参数 .仿真和发动机台架试验表明发动机在稳态和动态情况下 ,怠速得到了精确的控制 ,模糊控制方法对发动机参数的变化具有一定的鲁棒性 .
