Abstract :
A robust nonlinear controller is developed for the formation flying system. Using a nonlinear model directly, the Polynomial Eigenstructure Assignment approach is applied to complete controller design. The resulting controller can produce a closed-loop system with invariant performance over a wide range of conditions. Taking two sources of uncertainty, the robust D-stability is assessed by using the Finite Inclusion Theorem. The results show that the closed-loop system is fairly robust with respect to the uncertainties.
