摘要

By far, the manned and unmanned spacecraft Shenzhou-8, Shenzhou-9 and Shenzhou-10 have successfully completed automatic rendezvous and docking (RVD) with spacecraft Tiangong-1 for four times. During the process of RVD, the accurate and stable control of Shenzhou spacecraft is a difficult problem due to severe flexibility of solar panels, thruster plume disturbances, large system delay, the coupling between attitude and position control in the near range. In order to tackle this problem, first a characteristic model with multi-input and multi-output is derived in detail for spacecraft with flexible solar panels. The characteristic model is depicted as second-order difference equations with slowly time-varying parameters and is used for controller design. Besides mathematical derivation, computer simulation taking Shenzhou spacecraft as an example is performed to demonstrate the soundness of the established characteristic model. Secondly, based on the characteristic model, a golden-section phase-plane adaptive control method is newly proposed. In this method the ratio of golden section is used to calculate the parameters of phase plane controller. Finally, the in-orbit validation results for Shenzhou spacecraft are given. The results show that the proposed control method has strong rubustness with respect to disturbances, uncertainty of parameters and un-modeled dynamics. Besides that, this method can achieve less fuel consumption, is easy to be designed and can be applied to other jet control systems.
