柴油机模型参考自适应调速系统的研究

Researck on Model-Reference Adaptive Speed Control for Diesel Engine

首先根据自动控制理论建立了柴油机模型参考自适应调速系统的数学模型，并以李亚普诺夫方法设计自适应控制器，此后，在计算机仿真的基础上，分析了调速系统的动态性能。结果表明，在发动机调速系统中引入模型参考自适应控制原理，使系统性能得到明显提高。

In this paper, the mathematical model of a model-reference adaptive speed control system for diesel engine is deduced on the basis of automatical control theory. The adaptive governor is designed based on Lyapunov's stability theory. The dynamic behaviour of the system is analysed by means of computer simulation. The results demonstrate that introducing model-reference adaptive principle into the engine speed control system would evidently improve dynamic behaviour of the system.
