摘 要
柴油机在不同的工况、不同的工作环境和寿命周期内，其模型参数会有较大变化，因此传统PID方法用于柴油机电子调速控制有其不足之处。而模糊控制以人的经验为基础，运用模糊数学的方法进行控制计算，具有判决、推理、决策功能，它不苛求被控制对象具有精确的数学模型，对被控系统模型参数的变化有很强的适应能力，并能克服非线性因素的影响，具有良好的鲁棒性。因此，在柴油机电子调速系统中采用模糊控制技术具有其优越性。
本文建立了柴油机转速控制系统数学模型和执行器模型，设计了应用于柴油机调速的双输入单输出系统模糊控制器。针对转速偏差和扰动转速对柴油机喷油泵齿条位移变化量进行控制，既提高了控制精度，又简化了计算过程。最后借助有力的仿真工具MATLAB对柴油机转速控制系统进行了仿真研究。仿真结果显示，柴油机的转速控制效果得到了显著的提高，特别是在克服扰动方面效果明显。
本文的研究是开发实用的控制器的前期工作，更重要的是设计了一套较为完整的模糊控制算法，可为后续的研究提供软件技术和理论的指导。对深入认识和掌握柴油机转速控制器的设计步骤、进行控制器参数的优化、缩短电子调速起开发周期起到推进作用，也必然对柴油机电控技术的发展起到积极的作用。

Study on Fuzzy Control Algorithm
for the Double Cylinder Diesel Engine Electronic Speed Governor
ABSTRACT
Diesel engine will be great changes in different conditions or the working environment, and different life cycle to model parameters, so the traditional PID control method for diesel electronic speed has its disadvantages. Fuzzy control based on the human experience, use the fuzzy mathematics method for calculating the calculation, it has the decision, reasoning, decision-making functions, it dose not demand control object to have a accurate mathematical model of control system, the change of model parameters have strong adaptability and can overcome the non-linear factors, which has good robustness. Therefore, diesel electronic speed regulation system of fuzzy control has its advantageous.
This article builds the mathematical models of controller and speed control system to diesel engine，describing the dynamic characteristics of the running process of electronic speed governor of the diesel engine. Proposing the designing principles and methods of a fuzzy controller, The fuzzy controller adopts the double input and one output system to control the change of the EC velocity and location of the diesel engine spout, not only improving the control precision, but also simplifying the calculating process. Finally, this article uses the advanced Matlab toolbox to design the simulating model and simulate timely. By analyzing the simulating results show the great improvement of the speed control performance，especially to overcome the disturbance．
Research made in this thesis is the primary step in developing the actual controller, but the key point is the design and the experience on a fuzzy mathematics method ，thus can support the future work with the theory and software．By doing this，we can understand and master the design steps and optimize the controller’s parameters conveniently，shorten the developing time，so it will absolutely has great positive effects on the diesel engine electronic control engineering．
