Research output: Chapter in Book/Report/Conference proceedingConference contribution


Fractional control strategies for linearized relative-orbit dynamics are introduced and compared to standard proportional-derivative control strategies. Using fractional derivative operators in the controller introduces additional tunable degrees of freedom, affording more freedom in shaping the controlled trajectory. As a result, more optimal rendezvous trajectories can be achieved. Specifically, it is shown that fractional relative-orbit controllers outperform standard controllers in terms of several important performance measures such as settling time, overshoot, and control effort.
