应用P2P技术的互联网电机控制方法

针对在internet场景下的网络化控制系统(networked control system,NCS)通常要面临的两个问题:第一是不同网域内的控制节点无法直接通信;第二是internet环境下不稳定的网络链路质量会导致控制系统性能的下降甚至引发系统故障,首先提出一种基于端对端(peer—to-peer,P2P)技术的NCS系统,解决了internet范围上控制节点间的通信问题;然后设计了控制任务的共享功能:被控端节点可以向网络中发布被控对象的控制算法文件,而系统内的其他远程计算机都可以通过下裁控制任务文件成为远程控制器。上述方法实现了internet环境下NCS系统的拓扑动态性和数据链路的冗...

Summary:针对在internet场景下的网络化控制系统(networked control system,NCS)通常要面临的两个问题:第一是不同网域内的控制节点无法直接通信;第二是internet环境下不稳定的网络链路质量会导致控制系统性能的下降甚至引发系统故障,首先提出一种基于端对端(peer—to-peer,P2P)技术的NCS系统,解决了internet范围上控制节点间的通信问题;然后设计了控制任务的共享功能:被控端节点可以向网络中发布被控对象的控制算法文件,而系统内的其他远程计算机都可以通过下裁控制任务文件成为远程控制器。上述方法实现了internet环境下NCS系统的拓扑动态性和数据链路的冗余性,从而增强了系统的容错能力。最终通过实验证明了P2P技术搭建的NCS系统在internet范围上的拓扑动态性,且验证了冗余控制策略增强系统容错能力的有效性。

Aiming at two problems : one is devices of networked control systems (NCSs) located in different network domains can' t communicate with each other directly ; the other is that unstable data links on in- ternet would reduce the performance of NCSs, even lead to the failure, which always present in internet- based NCSs. Firstly a NCS structure was proposed using peer-to-peer (P2P) technology, so that the net- worked control units can obtain direct connections through internet, then the control task sharing function was designed--control side publishes its control algorithm file, and other remote computers act as remote controller by downloading the file. Benefiting from the dynamic topology and the relevant redundancy of data l
