Abstract:

针对飞行控制系统中状态向量不完全可测量的问题,设计了一种高增益神经网络自适应观测器.在常规高增益观测器的基础上引入径向基(RBF,RadialBasisFunction)网络自适应项,对建模误差和外界干扰进行在线估计.将高增益观测器与基于动态面的反步控制相结合,提出了一种神经网络自适应反步控制方法.引入一阶滤波器,避免了传统反步控制中的"计算膨胀"问题.基于Lyapunov稳定性理论,给出自适应输出反馈控制器和RBF网络权值向量的自适应律,并证明了闭环系统是半全局一致有界.从航迹角控制系统仿真结果可以看出,航迹角能够较好地跟踪指令信号,不受建模误差和外界干扰的影响,所设计的观测器具有良好的收敛性,控制系统具有较高的鲁棒性.
