In this paper, a flatness-based control strategy for multi-input multi-output linear time-varying systems is proposed in order to track desired trajectories. The control design, based on the use of an exact observer, leads to a polynomial two-degree-of-freedom controller without resolving Bézout’s equation in a time-varying framework. The proposed approach is illustrated with the control of a nonlinear model of the satellite SPOT-5.
