Abstract

Abstract: Cruise missiles facing complex constraints are prone to deviation from the intended trajectory due to disturbances and unexpected situations in flight. Based on solving the optimal control problem of trajectory optimization with pseudospectral method, the optimal closed-loop guidance is realized by continuous on-line trajectory reconstruction using the rolling time-domain strategy. The simulation experiments are also undertaken for the unexpected events and disturbances that may be encountered during flight to verify the capability and feasibility. Simulation results show that this method can meet the requirements of real-time and accuracy, and has good adaptability to different interference errors and task modification forms.
