This paper studies the design of network control system under forward and feedback random DoS(Denial of Service) attacks. A network predictive control scheme is proposed to compensate system forward and feedback channels block caused by DoS attacks, the random DoS attacks model is given. The predictive controller of a random time-varying DoS attacks network system is introduced, it predicts the control amount and the control compensator to select the latest control amount suitable for the controlled object. Finally, the stability criterion of the closed-loop system is given by using the pole assignment method.
