Query: Optimal Downlink-Uplink Scheduling of Wireless Networked Control for
  Industrial IoT   This paper considers a wireless networked control system (WNCS) consisting of
a dynamic system to be controlled (i.e., a plant), a sensor, an actuator and a
remote controller for mission-critical Industrial Internet of Things (IIoT)
applications. A WNCS has two types of wireless transmissions, i.e., the
sensor's measurement transmission to the controller and the controller's
command transmission to the actuator. In this work, we consider a practical
half-duplex controller, which introduces a novel transmission-scheduling
problem for WNCSs. A frequent scheduling of sensor's transmission results in a
better estimation of plant states at the controller and thus a higher quality
of control command, but it leads to a less frequent/timely control of the
plant. Therefore, considering the overall control performance of the plant in
terms of its average cost function, there exists a fundamental tradeoff between
the sensor's and the controller's transmissions. We formulate a new problem to
optimize the transmission-scheduling policy for minimizing the long-term
average cost function. We derive the necessary and sufficient condition of the
existence of a stationary and deterministic optimal policy that results in a
bounded average cost in terms of the transmission reliabilities of the
sensor-to-controller and controller-to-actuator channels. Also, we derive an
easy-to-compute suboptimal policy, which notably reduces the average cost of
the plant compared to a naive alternative-scheduling policy.
