Abstract: In order to endure the advancements in the technology of control systems, some challenges need to be conquered, mostly latency. An innovative approach termed the internet of things (IoT) is being proposed that has been inserted into this new technological development of network-based control systems organised with technical tools for evaluating closed-loop constancy and network-induced time-delays. A state-space prospective with pole-placement technique is developed in an IoT environment using edge devices to maintain the closed-loop constancy beneath unpredictable network time-delays. The benefits of the proposed system, which uses event-driven sensors, include improved plant state prediction through the use of predictive controllers and responsiveness when assessing network parameters such as steady state error, peak voltage, settling time, packet loss, etc. Consideration has been given to new research gaps and impediments, which are exemplified through simulation experiments that highlight the efficacy of the proposed approach.

Keywords: edge-IoT; internet of things; state-space controller; networked control system; NCS; latency; time-delay-compensator; stability; event-driven sensor.
