Energy management guidance method based on polynomial trajectory and storage medium

The invention discloses an energy management guidance method based on a polynomial trajectory and a storage medium, solves the problem that the speed and height exceed constraints in order to meet the requirement for a large range, and belongs to the field of aircraft guidance and control. According to the technical scheme, the method comprises the steps of obtaining a height third-order derivative and a lateral displacement third-order derivative under a kinematics equation; respectively describing the height and lateral displacement of the aircraft by using a five-order polynomial of time; determining all boundary constraints of the height and lateral displacement of the aircraft, determining polynomial coefficients in the two five-order polynomials, and then solving third-order derivatives of the two five-order polynomials; the attack angle change rate and the sideslip angle change rate of the control quantity are obtained, and then the attack angle and the sideslip angle of each guidance period are obtain
