模型跟踪和涡流控制在飞翼布局飞机上的应用

为增加小展弦比飞翼类布局飞机的操纵特性,并满足其对隐身性能的要求,将模型跟踪控制器和涡流控制器进行综合使用.模型跟踪是一种提高系统闭环响应并跟踪驾驶员指令的方法,通过此方法可使动态特性较差的飞机对动态特性较好的飞机输出进行跟踪,由此来改善飞机的动态特性.增加涡流控制可以进一步扩展模型跟踪控制的作用效果,涡流控制器使用变步长神经网络进行训练.结果表明,两种方法的综合使用可以有效地提高飞机的动态特性,通过增加涡流控制后,进一步增加了模型跟踪控制的作用效果.

Neural network control with model following for low aspect ratio flying wing based on vortex control

In order to improve the lateral ability of the low aspect ration flying wing aircraft and satisfied it's ability,two control methods were used.One solution to improve closed-loop tracking of pilot commands is to employ a model-following controller approach,whereby an aircraft with poor dynamics is made to track the outputs of a model of the same aircraft with good dynamics.An improved solution is the extension to combine the model-following controller with a controller the can augment the yaw power by effec...
