Abstract EN
Referring to the optimal tracking guidance of aircraft, the conventional time based kinematics model is transformed into a downrange based model by independent variable replacement.
The deviations of in-flight altitude and flight path angle are penalized and corrected to achieve high precision tracking of reference trajectory.
The tracking problem is solved as a linear quadratic regulator applying small perturbation theory, and the approximate dynamic programming method is used to cope with the solving of finite-horizon optimization.
An actor-critic structure is established to approximate the optimal tracking controller and minimum cost function.
The least squares method and Adam optimization algorithm are adopted to learn the parameters of critic network and actor network, respectively.
A boosting trajectory with maximum final velocity is generated by Gauss pseudospectral method for the validation of guidance strategy.
The results show that the trained feedback control parameters can effectively resist random wind disturbance, correct the initial altitude and flight path angle deviations, and achieve the goal of following a given trajectory.
