Abstract :
Recent flexible space structure control design studies have identified several important and to some extent surprising features of this class of problem suggesting that much simpler models than those obtained by traditional modal truncation methods may suffice for even very high bandwidth control systems. Implications regarding how one should do modeling and model order reduction for control and regarding how one may want to improve control design methods will be discussed.
