On Novel Adaptive Coordinated Control for Spacecraft Formation: An Adjustable Performance Approach

This paper investigates an adaptive coordinated control problem of spacecraft formation flying (SFF) system subject to uncertain mass and external perturbations. First, a general unified structure is proposed represent the adjustable performance functions like exponentially appointed-time convergent ones. Then, controller developed based on two-layer envelope characterize transient steady-state maneuvering behaviors quantitatively SFF system. Compared with existing approaches, prominent advantage one that preassigned position tracking consensus guaranteed simultaneously while maintaining scheduled configuration. Meanwhile, users can configure adjust convergence rate (like exponential or finite-time convergence) errors by choosing different parameters arbitrarily in for functions. Finally, group numerical examples are organized validated effectiveness approach.
