英文摘要
      In order to solve the optimal trajectory planning for approaching and tracking the specific position of the tumbling target , a multi-constrained optimal trajectory planning method based on inverse dynamics in the virtual domain (IDVD) is proposed. Firstly, the relative orbital dynamics equation of the chaser relative to the specific position of the target is established in the target body coordinate system and the relative attitude kinetics equation of the chaser relative to the desired attached-target coordinate system is also established. Secondly, the time/energy optimal programming model is established based on the inverse dynamic method considering the constraints of target shape, actuator size and sensor field; Then, the sequential quadratic programming (SQP) method is used to solve the planning problem. Lastly, the numerical simulations show that the chaser can arrive the expected states under the multi-constraint condition and verify the advantages in terms of computational efficiency compared with the Gauss pseudospectral (PS) method.
