Abstract :
Aiming at time constraint and trajectory phase angle constraint of aeroassisted space rendezvous, a approach guidance method belonging to the nominal guidance was presented. Due to initial trajectory errors and external disturbances existing in atmospheric flight, linear quadratic regulator was designed and computation method of weighted coefficient matrixes was given. Mathematic simulation example indicated that the designed regulator was strong robustness to the initial trajectory errors and external disturbances.
