以远程控制中基于特定网络的QoS(Quality-of-service)性能补偿为研究内容,首 先对QoS在线监测方法进行研究,进而探讨在给定系统性能指标和特定网络的QoS性能下的远程控制器设计问题,最后利用自行开发的远程控制系统,通过校园网对实验室三阶水槽液位控制系统进行远程控制实验研究,实验结果表明基于QoS性能补偿的控制方法具有较好的可行性.
An approach for networked three-layer water tank control system is advanced using a predictive compensation strategy to adapt the detrimental effect of networked QoS induced by communication networks. Firstly a dynamic on-line measurement method is presented for typical networked QoS performance. Secondly, a compensation strategy is designed for the given networked QoS and system performance targets. Finally, a relevant software is developed and tested through campus-wide net. The experimental results illustrate the effectiveness of the proposed scheme.
