A survey on robust stability and performance for networked control systems

This survey presents a comprehensive overview of networked control systems (NCSs), focusing on stability and performance guarantees under network-induced effects and constraints, mainly emphasizing on signal quantization, sampling, transmission delays, data losses and security. We first review fundamental concepts of NCSs, including modeling aspects of the control framework and common network-related assumptions. Subsequently, we examine stability-oriented results and their limitation with respect to performance issues. The survey then shifts to performance-oriented control of NCSs and discusses the trade-offs between achievable performance metrics and network limitations. Finally, we identify open issues and future research directions, including challenges associated with complexity issues, uncertainties on network conditions, practical implementation constraints and computational demands. This structured perspective provides a clear road-map for both understanding current NCS research and guiding future investigations.
