Tracking differential control guidance method for high-dynamic aircraft

The invention discloses a tracking differential control guidance method applied to a high-dynamic aircraft, and the method carries out guidance control through a three-dimensional guidance model considering the dynamic characteristics of an autopilot, and can optimize the problem of differential expansion generated in a conventional backstepping control process. Meanwhile, compared with a dynamic surface guidance law applying a first-order low-pass filter for solving the problem, the guidance control method adopts a tracking differentiator to perform differential processing on a virtual control variable generated in the backstepping design process, so that the obtained result has higher precision, higher control precision is generated, and the method is suitable for the dynamic surface guidance law of the dynamic surface. And guidance control with higher precision is realized. 本发明公开了一种应用于高动态飞行器的跟踪微分控制制导方法，该方法以考虑自动驾驶仪动态特性的三维制导模型进行制导控制，可以优化传统反步控制过程中产生的"微分膨胀"问题，同时相比于同样解决此问题的应用一阶低通滤波器的动态面制导律，所述制导控制方法采用跟踪微分器对反步设计过
