Research on Predictor-Corrector Terminal Guidance Law of Reentry Vehicle With Multiple Constraints
摘要
Abstract
To ensure the vehicle releasing store at expected angle and velocity accurately, the sliding-mode variable structure control was used to predict trajectory of vehicle in real time,and the vehicle was maneuvered under the control of corrector command to decelerate to reach the target point at expected angle and velocity. For the final height of 13 km and 3km,the trajectory and parameters of vehicle were computed respectively. The simulation results were compared. The results show that under the control with angle constraint, the final path angles satisfy the expected -30°,but the velocities are 1 550 m/s and 1 450 m/s respectively,higher than expected 1 200 m/s;by using the guidance law with angle and velocity constraints,the final path angle and velocity reach the expected value,and the angle of attack,the angle of bank and the over-loadings meet the limiting conditions. The predictor-corrector terminal guidance law with multiple constraints is in favor of store releasing accurately for reentry vehicle.关键词
