确定性网络控制系统的多步预测控制器设计

由于网络诱地时延的随机性，所以网络控制系统是一随机系统。对这样的随机系统，在网络诱导时延服从某一确定分布且其统计特性已知的情况下可以设计其随机控制器，否则只能设计其确定性控制器。在一定的假设条件下，通过在网络控制系统的源节点和目标节点分别设置一定长度的缓冲器的方法将网络控制系统中的随机时延转化为确定性时延，从而将原随机的网络控制系统转化为确定性的网络控制系统。基于线性时不变的被控对象，设计了确定性网络控制系统的多步预测控制器，所得刭的闭环系统是可镇定的，并且其控制器和观测器满足分离原理。以不稳定的倒立摆为对象进行了仿真研究，仿真结果表明本文方法的有效性。

The Multi-step Predicting Controllers for Deterministic Networked Control Systems

As network-induced delay is a stochastic variable,networked control systems are stochastic systems.For this kind of stochastic system,one can design its stochastic controllers when network-induced delay has a known probability distribution function,otherwise one can only design its deterministic controllers.On some assumptions,the method of placing a specific amount of buffer at source node and object node of the systems was used to transform stochastic time delay to deterministic time delay.The systems wit...
