摘　　要：针对不确定飞行器航迹角系统航迹倾角的跟踪控制问题,给出了有限时间跟踪控制的自适应迭代学习控制(AILC)方法。通过控制输入量舵面偏角来控制飞行器航迹倾角,使得飞行器航迹倾角的跟踪误差在有限时间内收敛于零,其中引入了典型的收敛级数来处理模型中的不确定部分,并利用李雅普诺夫(Lyapunov)稳定性定理给出了严格的稳定性分析。最后通过数值仿真验证了该方法的有效性。An adaptive iterative learning control(AILC)method based on finite-time tracking control is proposed for an uncertain aircraft track angle system to solve the tracking control problem of track angle.By controlling the input rudder surface deflection angle to control the aircraft track angle,the tracking error of the aircraft track angle and inclination angle converges to zero in a limited time.A typical convergence order is introduced to deal with the uncertain part of the model,with a strict stability analysis given by using Lyapunov stability theorem.Finally,the effectiveness by this method is verified by numerical simulation.
