Research On Networked Control Of Electromagnetic Formation Flying

Formation is a type of electromagnetic force based on the internal potential field force formation model of innovation, with the long-term course of non-orbiting spacecraft propellant consumption and pollution characteristics of the device, has gradually become the next generation of spacecraft formation flying research focus and cutting-edge topics.The background of this separation is Fractionated Space Systems which based on Electromagnetic Formation Flying, the electromagnetic formation flight dynamics modeling and control network has been studied, specifically as follows:Assumptions based on magnetic dipole in the electromagnetic force between the satellite formation models, based on the inertial coordinate system establish-ed under the Lagrange orbital dynamics equations, After the model of linear processing, linear track dynamic model has been relatively, the completion of its network control system in the formulation and conduct a model validation.In considering the case of system time delay, LMI model system has been established, using Lyapunov method for stability of the system has been proved, using electromagnetic force LMI toolbox design the network formation delay feedback control law to achieve the relative position of the control system.To address the robustness of the system external disturbance problem, robust control method is introduced to control the system, taking into account the delay and external disturbances under the premise of the system performance analysis and controller design. Solve the delay and the external disturbance on the impact of the stability control system, allowing the formation to maintain stability.
