Prof. Ocampo-Martinez received his doctoral degree in control engineering from the Universitat Politècnica de Catalunya (UPC), Barcelona, Spain, in 2007. In 2007-2008, he held a post-doctoral position at the ARC Centre of Complex Dynamic Systems and Control, The University of Newcastle, Callaghan, NSW, Australia, and, afterward, at the Spanish National Research Council (CSIC), Institut de Robòtica i Informàtica Industrial, CSIC-UPC, Barcelona, as a Juan de la Cierva Research Fellow. Since 2011, he has been with the Automatic Control Department (ESAII), UPC, as an Associate Professor in automatic control and model-predictive control. He spent visiting periods at MIT, Cambridge, MA, USA; the University of Delft, Delft, The Netherlands; the University of Cambridge, Cambridge, U.K.; the University of Siena, Siena, Italy; and ITBA, Buenos Aires, Argentina. His main research interests include constrained model-predictive control, large-scale systems management (partitioning and noncentralized control), process control, and industrial applications (mainly related to the key scopes of water and energy, and smart manufacturing under the IoT framework).

Talk title: Event-Driven Partitioning for Non-Centralized Predictive Control in Economic Dispatch of Interconnected Microgrids
Abstract:
This talk discusses a non-centralized model predictive control (MPC) approach to solve the economic dispatch problem in electrical networks. The proposed method operates in two stages. The first stage involves an event-triggered repartitioning mechanism that splits the network into a fixed number of non-overlapping sub-systems, namely microgrids in this context. The goal of this step is to create self-sufficient microgrids, capable of supplying their local loads using their own generation units. However, since the algorithm does not always guarantee that all microgrids will be self-sufficient, those that are not must form coalitions with neighboring microgrids. This coalition formation represents the second stage of the approach. By doing so, the overall economic dispatch problem is decomposed into smaller, coalition-based sub-problems, each of which is feasible. Although the solution derived from these sub-problems is feasible, it is sub-optimal compared to the centralized solution. Numerical simulations are provided to demonstrate the effectiveness of the proposed method.

Abstract:
Cardiovascular mechanics investigates the movement of the heart and of peripheral and central arteries, resulting from the pressure and flow of blood. Mechanical properties of cardiovascular tissue are the result of the interplay between tissue composition and the forces exerted on it. Ultrasound technology allows assessment of cardiovascular motion and of tissue stiffness. Cardiovascular tissue motion can be calculated from conventional ultrasound videos if coupled with image analysis methods, while tissue stiffness can be assessed with ultrasound elastography. The clinical usefulness of cardiovascular mechanics lies in the fact that it is more sensitive to early tissue changes due to ageing or disease, compared to anatomical tissue properties.

Abstract:
Prescribed-Time Stability in Switched Systems with Resets: A Hybrid Dynamical Systems Approach
We consider the problem of achieving prescribed-time stability (PT-S) in a class of hybrid dynamical systems that incorporate switching nonlinear dynamics, exogenous inputs, and resets. By “prescribed-time stability”, we refer to the property of having the main state of the system converge to a particular compact set of interest before a given time defined a priori by the user. We focus on hybrid systems that achieve this property via time-varying gains. For continuous-time systems, this approach has received significant attention in recent years, with various applications in control, optimization, and estimation problems. However, its extensions beyond continuous-time systems have been limited. In this talk, we address this gap and introduce a novel class of switching conditions for switching systems with resets that incorporate time-varying gains, ensuring the PT-S property even in the presence of unstable modes. The analysis leverages tools from hybrid dynamical system’s theory, and a contraction–dilation property that is established for the hybrid time domains of the solutions of the system. We present the model and main results in a general framework, and subsequently discuss two different problems: (a) PT control of dynamic plants with uncertainty and intermittent feedback; and (b) PT decision-making in non-cooperative switching games using algorithms that incorporate momentum, resets, and dynamic gains.
