摘要
针对天然气发动机怠速工作过程的非线性、时变性和不确定性,设计了一种模糊PID控制系统,并利用MATLAB所提供的Simulink工具进行了仿真。结果表明:在怠速工况下,模糊PID控制比数字PID控制转速波动小,控制效果好。
By taking account of nonlinearity,time variation and unsteadiness of idle process in CNG engine,a fuzzy PID control system for idle speed model is designed and simulated on Simulink toolbox of MATLAB.The results show that in idle speed mode,the fuzzy PID control is better than the digital PID control in lower speed fluctuation and of more effective control.
