Abstract
Wireless sensors and actuators offer benefits to large
industrial control systems. The absence of wires for commu-
nication reduces the deployment cost, maintenance effort, and
provides greater flexibility for sensor and actuator location and
system architecture. These benefits come at a cost of a high
probability of communication delay or message loss due to the
unreliability of radio-based communication. This unreliability
poses a challenge to contemporary control systems that are
designed with the assumption of instantaneous and reliable com-
munication. Wireless sensors and actuators create a paradigm
shift in engineering energy-efficient control schemes coupled with
robust communication schemes that can maintain system stability
in the face of unreliable communication. This paper investigates
the feasibility of using the low-power wide-area communication
protocol LoRaWAN with an event-triggered control scheme
through modelling in Matlab. We show that LoRaWAN is capable
of meeting the maximum delay and message loss requirements of
an event-triggered controller for certain classes of applications.
We also expose the limitation in the use of LoRaWAN when
message size or communication range requirements increase or
the underlying physical system is exposed to significant external
disturbances.
