Abstract
Satellite control is facing up new requirements in terms of high precision. Actuators satisfying these demands appear to be sensitive to the saturation. This can induce negative effects (i.e. oscillations, instability). To modify this situation an anti-windup strategy can be applied. The idea consists in introducing control modifications to keep the response close to the linear one. Two main architectures are used. The first one is based on a computation of a saturating feedback law. The second one is based on selecting an anti-windup incorporating a model of the plant. This work combines both approaches to compute a dynamic anti-windup. Simulations compare this anti-windup with other existing architectures.
