针对存在参数不确定性以及干扰的卫星编队飞行六自由度协同控制问题,提出了一种满足控制输入有界的自适应L2增益干扰抑制控制方法.该方法首先在不考虑干扰的条件下,针对卫星编队六自由度协同运动模型存在参数不确定性提出了一种自适应协同控制器;接着,考虑到系统存在干扰,进一步设计了具有L2增益干扰抑制能力且满足输入有界条件的自适应协同控制器.在MATLAB/Simulink平台上进行了仿真验证,结果表明,本文所提出的方法不仅能够对系统不确定性进行有效的自适应估计,还对干扰具备L2增益干扰抑制能力,同时具有良好的过渡品质.
Aiming at the six-degree-of-freedom cooperative control of satellite formation flight with parameter uncertainties and interferences, an adaptive L2-gain interference suppression control method that satisfies the control input boundedness is proposed. Firstly, In this paper, an adaptive cooperative controller is proposed based on the parameter uncertainty of the six degrees-of-freedom coordinated motion model of satellite formation. Then, considering the existence of interference in the system, adaptive coordination with L2 gain interference suppression and satisfying the input bounded condition is further designed Controller.The simulation results on MATLAB / Simulink platform show that the method proposed in this paper can not only effectively estimate the system uncertainties, but also have L2 gain interference suppression capability and good Transitional quality.
