| 摘 要： | 研究了一种基于神经网络的航空发动机全包线PID控制器设计方法。首先在全包线内选定若干典型工况点,并通过遗传算法离线优化PID控制器参数。然后通过BP神经网络训练建立飞行高度和马赫数与PID参数的非线性映射关系,亦即建立起基于神经网络的航空发动机全包线最优PID控制器。最后,将该控制器应用于某型涡扇发动机稳态控制和飞行过程控制仿真,与原控制器比较,控制效果获得有效改善。

| Abstract: | An aero-engine optimal PID control scheme was presented,which was suitable for the engine whole envelope with a neural network approximation.Firstly,the optimal PID controller parameters were designed by genetic algorithm(GA) for a certain turbofan engine simplified real-time simulation model around some design-points.Then according to these optimized PID controller parameters,a neural network approximation was trained to imitate the relation between the parameters(Kp,Ki,Kd) of local optimal controllers and... |
