网络控制系统调度与控制综合设计研究综述

Survey on co-design of scheduling and control in networked control system

网络控制系统的设计需同时考虑信息调度和控制性能两个方面。针对网络控制系统中这两方面的综合设计,首先分析了网络控制系统的信息调度研究现状,阐述了现有控制网络调度算法的工作方式和特点。接着从提高网络控制系统综合性能的角度,分析和评价了网络控制系统中调度与控制综合设计的研究成果。最后,提出以兼顾控制性能质量(QoP)和网络服务质量(QoS)为目标的网络控制系统综合性能优化是系统设计的重点,并对网络控制系统综合设计研究的发展方向予以展望。

The performance of networked control system （NCS） not only depend on the design of control algorithm but also on the network scheduling. Recent scheduling methods of NCS are presented respectively and their characteristics are also discussed. To improve the performance of NCS, some new approaches to NCS control and scheduling codesign are proposed to solve the conflicts between the two aspects. Lastly, some suggestions of new research trends are given that may improve the whole system performance, including the quality of control performance （QoP） and quality of network service （QoS） by synthesizing both control and scheduling schemes.
