This paper discusses a general form of a type-1 deadbeat serve system which nullifies the effect of the step disturbance and transfers the output to the step command signal within a finite time for a discrete-time linear time-invariant system. The type-1 deadbeat servo system is formulated by using the augmented system and its deviation system. Then, a general form of the type-1 deadbeat servo system is obtained. The controllability indices of the system are (n_1, …, n_m), where n_1≧…≧n_m. When the order r of the output is equal to the order m of the input, the controllability indices of the deviation system are (n_1+a, …, n_m+1) and the minimum settling time is n_1+1. When r<m, the controllability indices of the deviation system are not determined only by (n_1, …, n_m), and the minimum settling time is either n_1 or n_1+1.
