Disturbance attenuation for a class of distributed parameter systems

Abstract

This paper deals with the problem of robust stabilization and disturbance attenuation via measured feedback, for a class of dissipative collocated distributed systems with disturbances affecting both the input and the measured output. The proposed solution is based on a direct ℒ2-gain characterization which avoids the usual Riccati equation argument. For this purpose only strong stabilizability of the semigroup is required. A flexible slewing link is chosen as an application example. © 1997 John Wiley & Sons, Ltd.
