Antonella Ferrara – Multi-Scale Vehicular Traffic Control

Abstract:

The scientific, technological, social and economic impact of successful research in road traffic control is very significant, with immediate effects on safety, quality of life, environment, use of energy resources, and transportation costs. Yet, the development of effective methods and algorithms for road traffic management has to face notable methodological challenges. In addition, the type of traffic control strategies developed so far, the “classical approaches”, need now to be updated and adapted to consider the fast development in automotive technologies, traffic sensors, data processing, and communication. This lecture will address these aspects, starting from an overview of classical traffic control concepts to arrive at encompassing emerging research trends at different scales: from the microscopic scale of individual connected and autonomous vehicle control, to the macroscopic scale of road traffic control, also illustrating how the different scales can efficiently coexist in an advanced vehicular traffic control system. This will be done paying a particular attention to electric mobility, since it seems destined to become the dominant mobility paradigm in the next decades.

 Lucian Busoniu – Reinforcement learning and planning with applications to robotics

Abstract:

Powered by advances in deep neural networks, reinforcement learning (RL) has made great strides in the past decade, and its impact in control is increasingly being felt. This talk will begin by introducing the RL framework and some key algorithms. Afterwards, some recent applications of RL in active robotic mapping will be presented, in which the robot is controlled so as to obtain information about the map as quickly as possible. The map is represented either as an occupancy grid or a function defined over the robot’s operating area. A simpler variation of such a technique that only aims to find the maximum of the function will allow analysis of the convergence rate to the optimum. Time permitting, the talk will conclude with a model-based, planning framework counterpart for RL, with strong converge nce guarantees to the optimal control of general nonlinear systems with general costs.

Mircea Lazar – Physics-based neural networks for precision motion control

Abstract:

Currently, there is a growing interest in merging physics–based models and artificial intelligence to increase control performance for systems with complex dynamics. In this talk we will present a systematic method for embedding a known (or identified) physical model within a neural network and we will provide regularized training cost functions that address two key issues: competition among black-box and physics-based neural network layers, and robustness to non-training data. We will show that the developed physics-based neural networks (PNNs) model class is able to achieve improved accuracy with the same reliability as physical models. The relation of PNNs with physics-informed neural networks will also be discussed. To demonstrate the impact of PNNs on control performance, we will consider the problem of feedforward control design for precision motion control. Experimental results will be shown for two real-life applications: a coreless linear motor used in lithography machines and a hybrid stepper motor used in industrial printing machines. Such applications are indeed characterized by known physics-based motion dynamics and complex, partially unknown dynamics, e.g., due to electromagnetic forces or nonlinear friction. The PNN-based feedforward controllers achieve a factor 2 improvement with respect to conventional industrial feedforward controllers, while their design and tunning can be largely automated.

Sorin Olaru- Intermittent satisfaction of constraints and other relaxed notions of set invariance

Abstract:

Constraints handling and uncertainty characterization for dynamical systems represent a continuous interest in the control literature. In the first part of this talk, classic definitions of constraint satisfaction and set invariance will be reviewed, pointing to the latest developments with respect to some specific classes of dynamics as for example the time-delay ones. In the second part of the talk, the aim is to go beyond the rigid concepts by characterizing the intermittent constraint satisfaction along the evolution of the trajectories of a dynamical system. Two relaxed notions are introduced in this sense, one characterizing the validation of constraints within a given finite window and the other imposing the validation after a fixed number of time-steps following a violation. The constraint satisfaction with respect to a trajectory will then be extended to a set of constraints and tubes of trajectories. It is shown that all these notions can be accordingly anchored to the well-known positive set invariance thus offering a generalized framework for the analysis of dynamical systems in a set-theoretic framework.
