Abstract :
A robust feedback control design method is proposed for a class of uncertain time delay systems. Linear transformation is applied to convert the systems to new systems whose spectra embed all the unstable poles of the original systems for given stability margin. A feedback control is then designed based on the new systems and reflected back to the original systems. It is proved that the designed control can asymptotically stabilize both the new and the original systems provided a set of sufficient conditions are satisfied.
