High performance, robust control of flexible space structures

any spacecraft systems have ambitious objectives that place stringent requirements in terms of pointing and vibration control systems. Achievable performance is often limited because of the difficultly of obtaining accurate models for flexible space structures. To achieve sufficiently high performance to accomplish mission objectives in some cases will require the ability to refine the control design model based on closed-loop test data and tune the controller based on the refined model. A control design procedure is developed based on mixed...
