Recent years have seen increasing use of wireless technologies in diverse applications such as in environment monitoring, healthcare, and industrial monitoring and control. Due to advances in micro-electro-mechanical technology, small and low cost sensors with sensing, computation and wireless communication capabilities have become widely available. New technologies such as cyber-physical systems, smart cities, and the Internet of Things have been envisioned, where many everyday objects are connected together to form a network, with the potential to bring further improvements to the quality of life.
In industrial monitoring and control applications, the driving force behind using wireless technology is its lower deployment and reconfiguration cost. Here, reliable operation is of vital importance, as a delay in implementing appropriate feedback control actions can drive a dynamical system to instability and cause substantial damage. Nonetheless, even in such mission critical domains, the use of wireless technologies has become more prevalent, with industrial wireless sensor networks standards such as WirelessHART being developed.
In networked control systems, measurement and control signals are transmitted over channels or networks, which, in addition to bit-rate limitations, introduce effects such as packet drops and delays. Research interests of our group include estimation and control over wireless networks, event triggered and self-triggered estimation and control, and security in cyber-physical systems.&nb
