Wireless networked control systems, as the name indicates, employ wireless networks to interconnect their components, e.g. sensors, computing units, and actuators, in their implementation. Removing wires from control system implementations, the components can be more easily installed in spatial positions that are hard to access, and facilitate their deployment within large physical scales. This enables the expansion of control applications to new domains or objectives previously not attainable. However, as a trade-off, in a wireless networked control system, the transmission bandwidth is much smaller compared to a wired one. Besides, to achieve flexibility and mobility, some nodes may have energy supplies from batteries, which have limited capacity and are usually costly to replace. The limitations in bandwidth and energy supplies is a major problem when designing wireless networked control systems. The purpose of this thesis is to study how to guarantee pre-designed stability and performance under limitations of bandwidth and energy supplies, with the goal to enrich the control approaches for resource-aware industrial applications.
