基于蝙蝠算法整定PID的发动机空燃比控制研究

PID-setting engine air-fuel ratio control based on bat algorithm

为了提高发动机空燃比控制的精度,提出了一种基于蝙蝠算法整定参数的PID控制器,将此控制器应用于某单缸发动机的平均值模型中进行模拟测试,并加入了油膜补偿模型。仿真结果表明,与传统PID控制器相比,基于蝙蝠算法调整参数的PID控制器能更好地适应发动机系统的非线性和时变性特性,对瞬态工况下空燃比有更好的控制效果。

In order to improve the accuracy of engine air-fuel ratio control,we proposed a PID controller based on bat algorithm tuning parameters.Along with the oil film compensation model,this controller was applied to the average model of a single cylinder engine for simulation test.The results show that compared with the traditional PID controller,the PID controller based on the bat algorithm can better adapt to the nonlinear and time-varying characteristics of the engine system,and has better control effect on the air-fuel ratio under transient conditions.
