The invention provides a rocket vertical landing guidance method, device and equipment and a storage medium, and the method comprises the steps: obtaining the current height information and speed information of a rocket; the height information and the speed information are input into a fuel suboptimal switching function, an off function value and an on function value are obtained, the fuel suboptimal switching function is obtained after a damping parameter is introduced into a fuel optimal switching function, and the damping parameter is used for adjusting the width of an area between phase trajectories determined according to the fuel suboptimal switching function; inputting the off function value and the on function value into a switch control function to obtain a switching value of phase plane control; and determining a thrust value of the rocket based on the switching value, and performing vertical landing guidance on the rocket according to the thrust value. By improving a phase plane control method in the prior art, the technical problem that a system generates a flutter phenomenon or an overshoot phenomenon is solved.

    本发明提供了一种火箭垂直降落制导方法、装置、设备及存储介质,其中,火箭垂直降落制导方法包括:获取火箭当前高度信息与速度信息;将高度信息和速度信息输入燃料次优开关函数中,得到关函数值和开函数值,燃料次优开关函数为在燃料最优开关函数中引入消振参数后所得,消振参数用于调节根据燃料次优开关函数所确定的相轨迹之间区域的宽度;将关函数值和开函数值输入开关控制函数,得到相平面控制的开关量;基于开关量确定火箭的推力值,根据推力值对火箭进行垂直降落制导。本发明通过对现有技术中相平面控制法的改进,来解决系统产生颤振现象或超调现象的技术问题。
