Appointed-time attitude-orbit coupling control for distributed spacecraft formation
摘要
Abstract
This paper addresses the problem of appointed-time attitude and orbit coupled control for distributed space-craft formation with parameter uncertainties,external disturbances and requirements of prescribed performance.A low complexity cooperative controller was proposed based on the prescribed performance control method,which realized the spacecraft formation flying within the set time and the formation errors met the preset performance indexes.Firstly,an appointed-time performance function that can arbitrarily set the stability time of the system is introduced by using the concept of finite time stability.Secondly,by combining the appointed-time performance function with the prescribed per-formance control method,a appointed-time cooperative controller is designed to ensure the transient performance and the steady performance and finite-time stability of spacecraft formation control system.And the controller is independent of spacecraft mass and moment of inertia.Finally,the Lyapunov stability theorem is applied to prove the stability of the control system,and numerical simulation results show the effectiveness of the control law.关键词
