远程控制系统互联网传输时延预测算法的研究

Study on Internet delay Prediction Algorithm in Remote Control Systems

由于互联网传输时延的存在,远程控制系统的稳定性很难保证,互联网时延的精确预测在改善远程控制系统的动态性能方面扮演着重要的角色。从网络通信的原理出发,分析了互联网传输时延的构成以及其不确定性特征后,提出了采用随机过程AR模型预测不确定性的互联网传输时延的方法。最后通过预测时延仿真实验表明该方法的有效性。

Stability is hard to ensure due to Internet transmission time-delay in remote control systems over the Internet. The accurate prediction of the time-delay plays a key role in improving dynamic performances for remote control systems. After analyzing Internet communication features, the Autoregressive （AR） model is adopted to predict the uncertain Internet time-delay. The simulation results for time-delay prediction illustrate that the AR model provides a promising way to predict the Internet time-delay.
