Abstract :
In a multiple satellite formation control system, parameter variations and uncertainties have great effects on the relative position tracking precision. This paper proposes an adaptive design method with uncertainty compensation. An adaptive compensation scheme is presented to cancel the effect of the uncertainties. Adaptive update laws are employed for estimation of the uncertain parameters. A state feedback control law is designed to control the nonlinear satellite structures such that the relative motion is retained.
