摘　　要：针对空间翻滚目标的逼近与跟踪控制,建立了适用于任意抓捕部位的相对姿态轨道耦合动力学模型,设计了具备测量不确定性和干扰补偿、抖振抑制等能力的鲁棒双滑模面控制律,分析并建立了测量误差在系统中向控制输入的传播模型。在充分考虑测量不确定性、控制干扰、输入受限等条件下,分别对单滑模面控制律和双滑模面控制律进行了仿真验证和对比分析,结果验证了双滑模面控制律在测量不确定性和未知干扰系统中具备更优的控制性能,收敛稳定更快,精度更高。According to the particular demand to the approaching and tracking control of the space tumbling target and the applicability of arbitrary captured position, a coupled dynamic model of relative attitude and orbit is estab- lished. Under the measurement uncertainties and disturbances, the robust dual sliding-mode surface control law with the ability of disturbance compensation and jitter suppressing is designed. The error propagation model from the measurement to the input control quantity in the system is analyzed and established. The single and double slid- ing-mode surface control laws are simulated separately, under the conditions of the measurement uncertainty, con- trol disturbance and input constraint. The result verified that the dual sliding-mode surface control law has the better performance for the system with measurement uncertainty and disturbance.
