Yx. Yao et al., PARAMETERIZATION OF OBSERVERS FOR TIME-DELAY SYSTEMS AND ITS APPLICATION IN OBSERVER DESIGN, IEE proceedings. Control theory and applications, 143(3), 1996, pp. 225-232
The paper addresses the design of observers for systems with time dela
y. A factorisation approach is used to parameterise all observers for
such systems. The necessary and sufficient condition of existence for
observers is obtained. Based on the results in the parameterisation of
observers, the estimation error dynamics is also parametrised. A desi
gn example is given to illustrate the proposed parameterisation proced
ure.
