摘要:
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.

Abstract:
In order to improve the accuracy of engine air-fuel ratio control (A/F control), a PID controller based on bat-algorithm tuning parameters is proposed. This controller is applied to the average model of a single cylinder engine for a simulation test, with the oil film compensation model added. The simulation 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.
Key words:  A/F control  bat-algorithm  PID parameter setting  oil film compensation  mean value model
