Research on state feedback guidance method based on H-V standard trajectory

Based on the principle of LQR linear quadratic controller, this paper designs a state feedback regulator for the reference H-V standard trajectory of the long-range glider under the condition of considering various deviations. The simulation results show that the LQR linear quadratic regulator designed in this paper can effectively eliminate the deviation caused by factors such as height, trajectory inclination angle, and aerodynamic parameter disturbance. The actual flight H-V trajectory can track the ideal trajectory well. The tracking controller has strong robustness.
