摘　　要：针对汽车电子节气门具有很强的参数不确定性、时变性和非线性,难以建立准确的数学模型等特点,采用了一维云模型和常规PID相结合的控制方法建立了节气门控制器,分别运用PID型云模型控制器和常规PID控制器对节气门模型进行仿真;最后,通过Matlab/Simulink仿真实验,结果表明与常规PID控制器相比较,PID型云模型控制器能够显著提高节气门的快速性、稳定性和鲁棒性。As the automotive electronic throttle has strong parameter uncertainty,time-varying,nonlinear and it is also very difficult to establish a precise mathematical model,which designs a throttle controller based on one dimensional cloud model and the conventional PID control algorithm and establishs one dimensional cloud model PID controller to control the models which are different from the spring torque and the friction torque. Using PID cloud model controller and conventional PID controller to simulate the throttle model. Finally,MATLAB/Simulink results show that by comparing with the conventional PID controller,the PID cloud model controller can significantly improve the throttle about the rapidity,stability and robustness.
