The generalized definitions of steady-state error for single input single output feedback systems in [6, Truxal] are extended to the case of multivariable (m input-m output) systems. And using this concept, a more practical definition of the system type of the steady-state error is presented. Also, it is shown that the system type studied so far in [2]-[5] is a special case of that given in this paper.
