摘　　要：随着导弹数字控制技术和网络通信技术的发展,数据总线传输方案越来越受到重视。以数据总线为核心的导弹总线网络控制系统能够有效克服传统通信网络的弊端,改善系统性能,然而由于信息传输分时复用通信网络,系统延时是不可避免的。本文利用接收缓冲区,将时变延时转变为固定延时,并在此基础上,对导弹总线网络控制系统提出滑模预估控制器设计方法。仿真结果表明,这种设计方法是有效的。With the development of the missile digital control and network transmission technologies, the data bus transmitting scheme has been paid more and more attentions. And it can efficiently simplify the system structure, reduce the initial mass and increase the reliability. Communication networks inevitably introduce delays, not only due to limited bandwidth, but also due to overhead in the communicating node and in the networks. It makes the closed system time-invariant by introduction of buffers at the controller and actuator nodes. And a design method of sliding mode predicting controller for missile networked control systems is presented. The simulation result shows the effectiveness of the scheme.
