Scheduling-Control Co-Design for WirelessHART Networks
WirelessHART is an open standard for wireless sensor-actuator networks in process monitoring and control. Recent years have seen initial success in real-world deployment of control systems over WirelessHART networks. Due to stringent bandwidth constraints in WirelessHART networks, it is important to develop a wireless transmission scheduling and control co-design approach to optimize the control performance subject to network resource constraints. This paper addresses the co-design problem of determining the optimal sampling rates of multiple feedback control loops sharing a WirelessHART network.
