摘　　要：面向在轨服务提出了一种组合体航天器的参数在轨辨识与控制方法。针对辨识参数估计误差相对较大、环境存在干扰力矩以及控制输入受限的情况,设计了一种自适应变结构控制算法,实现组合体航天器对干扰和参数不确定的鲁棒性,并保证了快速和精确的响应。仿真结果表明设计方法有效,能满足控制指标要求。A method used in the attitude control of combined spacecraft was proposed based on parameters identification in this paper. Considering the situations that the estimation error of parameter identification was relative large, there was disturbance torque, and control input was limited, an adaptive variable structure control algorithm was studied to realize the robust of the spacecraft assembly to the disturbance and parameter uncertainty, which could assure fast and accurate response. The simulation results showedthat the approach proposed was effective which could meet the control requirement.
