Abstract:

Industrial applications are driving a surge of research with the goal of enabling the implementation of control systems over wireless communication channels. A major challenge in this context is the reduction of power consumption in the sensor nodes of the system while guaranteeing the stabilization of the plant under control. 

 In this seminar I propose an implementation of control systems in which measurements from different sensors do not need to be synchronized in time and are aperiodically transmitted. Furthermore all the communications between sensors and controller, and vice-versa, require only the transmission of one bit of information. The proposed implementation is based on the idea of measurements and transmissions being triggered by local events at the sensors. From a practical perspective, this approach can aid at greatly reducing power consumption of wireless sensors in a control system by not only reducing the amount of transmissions, but also the time the sensors spend listening for communications from other sensors or the controller.

Biography:

Manuel Mazo currently works as a post-doctoral researcher at the innovation center INCAS³ and the University of Groningen, both in the north of The Netherlands. Manuel earned his Ph.D. in Electrical Engineering from the UCLA in 2010 under the supervision of Prof. Tabuada, and was a recipient of a Henry Samueli Scholarship and a joint scholarship from the Spanish Ministry of Science and Education and the University of California. Prior to UCLA, he earned engineering degrees from KTH (Sweden) and the Technical University of Madrid (Spain). Manuel’s research interests are in cyber-physical systems, hybrid systems, distributed control, embedded control software synthesis, and the application of these theories in sensor-actuator networks.
