摘　　要：为了更好研究柴油机动态调速工作过程,在实验的基础上,采用MATLAB/S imu link仿真平台和FuzzyLogic Toolbox工具箱建立柴油机准线性控制模型,采用增量型PID和自适应模糊PID对此模型进行控制仿真,分析油门突变和负荷突变时不同控制算法对转速稳定性的控制效果,综合各自算法的优缺点指导了实际控制软件的编写。发动机台架实验测试结果表明,发动机稳态调速率小于2.500/,符合各类常规动力设备的调速要求,并实现对LR6105Q型柴油机的全程调速和两极调速的功能,达到了与发动机匹配主机的动力特性要求。In order to understand the dynamic process of speed governor of diesel engine, a quasi-linear dynamic model with MATLAB/Simulink simulation platform and Fuzzy Logic Toolbox is proposed based on the experiments. Meanwhile, simulation was conducted by adopting the model including increment PID control and self-adaptive tuning of fuzzy PID control. A comparison in speed stability with different controlling arithmetic was analyzed when fuel pedal or load suddenly changes. The outcomes of simulation are used to guide the experiment. Experiments showed that the steady-state governing rate is less than 2.5%, satisfying the demand of normal dynamic equipment, and realizing two-range governor mode and full-range governor mode, and finally meeting the dynamic demand of engine matching.
