W. Chen et al., AN OUTPUT TRACKING CONTROL FOR NONLINEAR-SYSTEMS WITH UNCERTAINTIES AND DISTURBANCES USING TIME-DELAY CONTROL, Cybernetica, 40(3), 1997, pp. 229-237
For precise tracking control of a class of nonlinear system with uncer
tainties and disturbances, an Time Delay Control (TDC) method using ma
tching condition and relative degree of a class of uncertain nonlinear
system, is proposed. A sufficient condition which guarantees the trac
king control is given. From the derivation, we can find that the basic
reason why produce the bounds of asymptotic errors is the uncertainti
es.
