Spacecraft formation flying is an enabling technology and attractive alternative to single-spacecraft systems. In addition to being reliable and upgradable, spacecraft formations will provide a means of performing a variety of tasks and missions that cannot be performed by a single satellite. Associated with spacecraft formations are a number of new and challenging problems in the area of spacecraft dynamics and control. Active control systems are required to maintain relative configurations to the accuracies demanded by tasks such as high resolution Earth and deep space imaging. In formation missions involving micro-satellites, fuel efficiency is of paramount importance. This study presents a number of control laws well suited to micro-satellite scale formation missions. The control laws are derived using control techniques such as linear quadratic regulator design, feedback linearization and disturbance accommodation to bring fuel requirements into a range feasible for micro-satellite missions. The CanX-4/5 mission, developed by the Space Flight Laboratory at the University of Toronto Institute for Aerospace Studies, is of particular interest. A control law that accommodates propulsion and attitude subsystem limitations associated with the CanX-4/5 system is presented, along with an extensive body of simulation data to aid in the mission design process.

The fundamental control challenges associated with Spacecraft Formation Flying (SFF) can be classified into two categories: (i) trajectory design and (ii) trajectory tracking. In this research, we address these challenges for several different operating environments. The first part of this research focuses on providing a trajectory generation and an adaptive control design methodology to. Different formation flying architectures and their relevant control design techniques are discussed in many research works. 14,15 Some recent studies on control techniques for spacecraft formation.

The key challenge of this approach, namely ensuring the proper formation flying of multiple craft, is the topic of this second volume in Elsevier’s Astrodynamics Series, Spacecraft Formation Flying: Dynamics, control and s: 2. In this paper, finite-time attitude coordinated control for spacecraft formation flying (SFF) subjected to input saturation is investigated. More specifically, a bounded finite-time state feedback control law is first developed with the assumption that both attitude and angular velocity signals can be measured and transmitted between formation members.
