摘要
网络控制系统(NCS)是近年来控制领域的一大新兴热点,将控制理论与信息化结合在一起,己经在控制领域中得到广泛的重视,但是网络具有随机时延的特点,是网络控制应用的一大技术难点。本文结合磁悬浮系统(高阶不稳定系统),利用Truetime网络仿真工具,提出了一种改进的预整定Smith预估控制器并结合了改进的专家PID控制,对磁悬浮小球控制系统进行了仿真研究,取得了良好的控制效果。
Network Control System （NCS） is an emerging hot research topic in the field of control theory, resent years. It is a combination of control theory and information technology, it has draw attention in the field of control theory. Yet, time delay is the disadvantage of the network. This paper presents a combination of advanced expert PID control and a modified Smith predictor for the networked control system of a magnetic ball. Simulation results are also given based on the Truetime software.
