小型柴油机控制系统与控制策略研究

Research of Control System and Control Policy for Small Diesel Engines

基于小型柴油机的特性参数,通过对非增压柴油机模型进行合理修正,得到了一个合适的数学模型;采用PID参数模糊自整定控制算法进行了怠速控制器的设计,并仿真得到了较常规PID更优的控制效果,结果误差在理论允许的范围内。能够为小型柴油机的技术升级提供有效依据和技术参考。

Based on /he parameters of the mini-type diesel engine, a suitable mini-type diesel mathematical model is founded by modifying a non-pressurize diesel engine model in this paper; Controller module is designed by using fuzzy self-tuning PID control algorithm, and it makes the idle speed control system of better control efficiency than conventional PID control does. We get results in theory error margin. It provides the valid basis and the technique references for the technique upgrade of the mini-type diesel engine
