Predictor-corrector terminal guidance logic of gliding vehicle with final states constraints

The variable structure guidance logic with terminal angles constraints was used to estimate the trajectory, if the terminal predicted velocity was larger than the expected value; a maneuvering correct command was generated by the deceleration theory. So, the guidance logic with terminal angles and velocity constraints based on predictor-corrector was designed. Analyzed the results of two cases for final altitude 13km and 3km, it found that the gliding vehicle could get to the target point with the multiple angles and velocity constraints by the control of designed guidance law, and the maneuvering trajectory could improve the terminal breakthrough for the vehicle.
