Abstract

This article presents the development of a dynamic output feedback controller designed for a benchmark model of a satellite rendezvous system that has both uncertainties and external perturbations. The investigated method renders the controller-synthesised closed-loop rendezvous system into an α-strictly negative-imaginary system. The demonstration of robust stability for the satellite rendezvous system in the presence of uncertainties is achieved by employing the DC loop gain condition associated with negative-imaginary systems theory. Moreover, the closed-loop system, synthesised with negative-imaginary characteristics, demonstrates noteworthy time-domain performance. The simulation results of the article show the effectiveness of the output feedback control method in satellite rendezvous.
