An event-trigger control scheme for spacecraft attitude control

Abstract

This report discussed on the proposal of event-trigger control design scheme for spacecraft attitude stabilization problem to reduce communication burden between spacecraft attitude controller and actuator. Both controller and event-trigger controller are designed simultaneously in order to compensate the measurement error caused by event-trigger mechanism. Two different strategies are proposed, ie. fixed threshold strategy and relative threshold strategy. Models are simulated using Matlab Simulink. The event-trigger scheme is proved by Lypunov analysis that the angular velocity error and attitude tracking error will converge to an arbitrary small residue value around zero.
