In this paper, the dynamic matrix control (DMC) problem is investigated for a class of networked control systems (NCSs) with time-delay and packet disorder- ing. By analyzing the time sequence of packets, a reordered approach is presented for packet disordering, where the phenomenon of packet disordering occupies both in the controller side and actuator side. Based on the proposed reordered approach, a modified DMC algorithm is presented to design the stabilizing controller. Moreover, a sufficient condition to ensure the closed-loop system stable is derived. Finally, an illustrative example is given to demonstrate the effectiveness of the proposed method.
