| 摘 要： | 为了解决基于以太网的网络控制系统中数据传输时延给控制品质带来不良影响的问题，从融合控制技术与网络通信技术的角度出发，提出了一种新的控制方案，即运用在线时延估计方法来估计出网络控制回路中的时延特性．在此基础上，结合以太网优先级技术，采用LQG控制算法对网络控制系统进行最优控制设计，并通过实验仿真结果证明了上述方案的有效性．

| Abstract: | In order to solve the problems caused by uncertain delay in networked control systems based on ethernet,a new control scheme that integrates control technology with communication technology was brought forward,which is composed of two parts.First,originated from the idea of online delay estimation,the delays characteristics on line is to be obtained.Then a scheme based on LQG controller combined with application of the priority was designed to achieve desired real-time performance.The simulation result illustrated that the proposed control design is effective and the performance of the systems is satisfactory. |
