Improvements in communication networks, and the massive diffusion of Internet have allowed the development of a new idea of control systems, where distributed controllers, actuators, sensors, and plants are connected together through shared communication channels. This has the major advantage of reducing deployment and maintenance costs, but it introduces new challanges on the control side. In fact, non-deterministic communication networks suffer from delays and packet drop-outs, which might cause degradation in performance, or even instability of the closed-loop system.
My research is focused on how it is possible to deal with these two problems. In particular, whereas a lot has been done for linear systems, much attention has not been paid yet on nonlinear ones. Moreover, it would be interesting to analyze how the communication between plant and controller can be minimized in order to satisfy specific constraints, e.g. energy constraints, bandwidth limitations.
I am also working with Nonlinear Model Predictive Control and Optimization Problems. Furthermore, I am interested in Robotics and Soft-Computing.
