Networked control systems (NCSs) have played a key role in Internet of Things (IoTs) to realize the vision of a fully interactive and responsive intelligent environment. However, traditional NCSs cannot address the challenges of big data collection, storage and analysis brought by large-scale IoTs applications. Thanks to the rapid development of cloud computing and control theory, a new paradigm of NCSs named cloud control systems (CCSs) has been proposed to address the challenges. Since proposed in 2012, it has drawn wide attentions from industry and academia. In this brief, we survey the recent advances of CCSs. Particularly, we present a taxonomy of existing results for CCSs, which include cloud control perspectives of traditional control techniques, security and privacy of cloud-based control, and CCSs for industry automation. We discuss each category in depth by comparing and contrasting different approaches subsequently. Finally, some future directions of how to design more efficient and practical CCSs have been discussed.
