✦ Synopsis

This paper addresses the problem of designing sliding control of uncertain systems which are free of chattering and result in smooth control signals. Both state and output feedback are considered. The proposed approach relies on some appropriate prediction error and can be easily applied to modify the usual state feedback VSC for chattering avoidance. It can also be applied for devising new output feedback VSC laws. The robustness improvement, with respect to unmodelled dynamics, even allows one to reconsider the so far rejected utilization of approximate differentiators for VSC output feedback. The theoretical results are illustrated by simulations. An experimental evaluation is briefly discussed. 1997 by John Wiley & Sons, Ltd.

A control design method is proposed to design controllers to achieve global sound pressure attenuation for noise of narrow-band frequencies in a one-dimensional acoustic duct system. This method combines a linear-quadratic-gaussian (LQG) theory with an internal model principle to design internal mod
