【 摘 要 】

For the network control system with data-dropout and induced delay，this paper introduced a method of compensation． First the problem of packet loss can be modeled as a Bernoulli random sequence，a control prediction generator is then designed to calculate the controller for each different delay，and the delay compensation controller can choose the corresponding controller for the controlled object． And then we can get a random control system model． We will study the stability of the obtained system and the expression of the network delay compensation controllers according to Lyapunov stability theory． At last a simulation is designed to show that this method can effectively overcome the effect of long time delay and packet loss on the system，improve the dynamic performance of the system．
