| 摘 要： | 点火提前角控制是天然气发动机控制的最重要内容之一,精确控制点火提前角涉及到发动机运行的动力性和经济性。对此,开发采用BP神经网络控制的方法来实现天然气发动机的点火提前角控制问题,并基于发动机平均值模型进行了神经网络的MATLAB在线仿真。结果表明:点火提前角最大绝对误差0.4°CA,最大相对误差1.5%,该优化控制模型能准确地获取天然气发动机最佳点火提前角。

| Abstract: | Ignition timing influences the performance of a CNG fuelled engine strongly,such as power output,emissions and fuel economy.Aiming to this subject,BP neural network is developed to solve the problem of SA control in CNG engine,and then emulates it on-line under MATLAB Software Platform on mean value engine model.The result indicates that the optimized control model could accurately forecast the ignition timing of the CNG engine. |
