Abstract
To study the guidance law for vertical-recovery landing phase of rocket,the guidance law was obtained by solving the problem of saving most fuel.The continuous optimization problem was transformed into a second-order cone program(SOCP)convex optimization problem.During each guidance-period,the guidance law was obtained by calculating the optimal trajectory to guide the rocket to the preassigned target and achieve vertical soft landing.The method has strong adaptability to the initial state variables deviation and aerodynamic disturbance during descending.The simulation of three examples was carried out.The results show that the convex optimization method has deterministic convergence properties,and it is an efficient solving method compared with Radau pseudo-spectrum method.The setting of parameters by the method is easy,and it meets real-time guidance requirement and can be implemented for on-line application.关键词
