Yy. Cao et al., DELAY-DEPENDENT ROBUST STABILIZATION OF UNCERTAIN SYSTEMS WITH MULTIPLE STATE DELAYS, IEEE transactions on automatic control, 43(11), 1998, pp. 1608-1612
This paper deals with the problem of robust stabilization for uncertai
n systems with multiple state delays. The parameter uncertainties are
time-varying and unknown but are norm-bounded, and the delays are time
-varying. A new method for achieving robust stabilization is presented
for a class of uncertain time-delay systems via linear memoryless sta
te feedback control. The results depend on the size of the delays and
are given in terms of several linear matrix inequalities.
