✦ Synopsis

Design of observers and observer-hased controllers for linear, discrete control systems with fast and slow modes are considered in this paper. The time separation is expressed in terms of an inequality relating norms of system submatrices. It is shown that reconstruction of fast and slow states can be accomplished by a full-order observer, the gains of which are computed using a two-stnge procedure. Then, provided that the fast subsystem is asymptotically stable, it is shown that a low-order observerbased controller can be designed with independent gain matrices to stabilize the origiual discrete system. The theoretical analysis is illustrated by a ninth-order boiler system model.

We consider a control design problem for a class of mismatched uncertain systems. The uncertainty is (possibly fast) time-varying. A new way of characterizing the structure of uncertainty is submitted. A class of robust controls, which is based on the possible bound of uncertainty, is proposed. The
