Paper Abstract

A dynamic feedback linearization control approach is designed in this paper for the pitch angle trajectory control and vibration suppression of a flexible spacecraft. Using the extended state observer, the pitch rate and entire unknown dynamics can be estimated, so only pitch angle is needed to measure in the feedback linearization control. The expression of the control law is simple, and few observer parameters need to be tuned. These all reduce the engineering difficulty greatly. The design of this control law does not depend on elastic modes included in the spacecraft model. Simulation results are presented to show that, the control law designed can ensure that pitch angle maneuver to its target precisely and smoothly, and elastic vibration is suppressed effectively.
