Simple output feedback adaptive control based on passification principle.

SUMMARY This paper deals with the output stabilization of time-delay systems with sector-bounded nonlinearity and disturbance. In this paper, we will consider the problem of absolute stability for a time-delay systems class, which can be represented as a feedback connection of a linear dynamical system with unknown parameters and an uncertain nonlinearity satisfying a sector constraint. Control algorithm providing exponential stability of equilibrium position without disturbance and L ∞ -stability for disturbed systems is proposed for a class of output. Obtained results are validated with the aid of computer simulation of the two-stage chemical reactor control. Copyright © 2013 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
