N2 - An iterative reentry guidance method based on angle of attack profile correction and bank reversals search is proposed to meet constraints on the time and heading angle of the mid-terminal shift in hypersonic vehicle. To address the time and range constraints of the gliding phase, a dual-parameter drag acceleration profile with corridor-boundary interpolation is designed in the longitudinal-plane. The heading angle constraint is transformed into a nonlinear optimization problem of the lateral-plane bank angle reversal point, and a bank angle reversal search strategy based on simulated annealing-sequential quadratic programming (SA-SQP) hybrid optimization is developed. Furthermore, in order to reduce the coupling interference error between longitudinal and lateral guidance, a predictor-corrector method with real-time correction of the angle of attack profile is proposed to improve the guidance accuracy. Numerical simulation experiments verify that the algorithm can satisfy the constraints of flight time, range, heading angle, etc., and has high guidance accuracy and strong mission adaptability. Monte Carlo simulations further validate the adaptability and robustness of the method against initial state deviations and process disturbances.
