“…The current work extends the results in our preliminary work [24]. The work [24] concluded that event-driven or deadlinedriven approaches do not necessarily perform better than one another (in an LQG performance sense). Here, we propose a novel switching strategy that is guaranteed to result in a better performance than that of event-driven and deadlinedriven approaches by switching between them.…”

“…In this paper, we provide control policies that are guaranteed to improve over both optimal event-driven and deadline-driven strategies as proposed in [24], in the sense that the performance index (2) is smaller or equal. Simulation results will evidence that significant improvement can be realized.…”

“…Such event-driven strategies (differing from state-dependent event-triggered control, see e.g. [22], [23]) consider that the control input is immediately updated after the delay, and therefore the update intervals are equal to the stochastic delay [24]. Results for systems with stochastic parameters [25] can be used to find optimal control strategies for this case.…”

Packet-Drop Design in URLLC for Real-Time Wireless Control Systems

et al. 2019

View full text Add to dashboard Cite

In real-time wireless control systems, ultra-reliable and low-latency communication (URLLC) is critical for the connection between the remote controller and its control objective. Since both transmission delay and packet loss can lead to control performance loss, our goal is to optimize control performance by jointly considering control and URLLC constraints in this paper. To achieve this goal, we formulate an optimal problem to minimize control cost by optimizing the packet drop and wireless resource allocation. To solve the problem, we analyze the relationship between communication and control. Then, based on the relationship, we decompose the original problem into two subproblems: 1) an optimal packet-drop problem to minimize control cost and 2) an optimal resource allocation problem to minimize communication packet error. Finally, the corresponding solutions for each subproblem can be obtained. Compared with the traditional method only considering the communication aspect, the proposed packet-drop and resource allocation method shows remarkable performance gain in terms of control cost.INDEX TERMS URLLC, real-time wireless control, packet drop, wireless resource allocation.
