Time Delay Control(TDC) is a robust nonlinear
control scheme that uses Time Delay Estimation(TDE). The
TDC has a very simple structure, and its application on a real
system needs its stability he guaranteed. The existing work has
proposed sufiicient stability condition of TDC for inputloutput
linearizable plants in that it has been assumed that time delay
was infinitesimal. However, it is impassible to implement
infinitesimal time delay in a real system. Therefore, in this
research we propose a new sufiicient stability condition of TDC
for inputloutput linearizable plants with finite a time delay. It
can be verified hy simulation results that the existing sufiicient
stability condition fails even under small time delays while the
proposed condition performs well
