Here we consider the problem of stabilizing a finite-dimensional, stab
ilizable and detectable, linear time-invariant (LTI) plant in the sens
e that the plant state goes to zero while: the controller state conver
ges. With r the dimension of the plant output, we show that there exis
ts a nonlinear time-invariant controller of order r + 3 which stabiliz
es all such systems. (C) 1998 Elsevier Science B.V. All rights reserve
