Duration: half day (3 hours)
This tutorial addresses one of the timely topics in the field of autonomous multi-vehicle systems for Smart Cities and Industry 4.0: formation control and collision avoidance for multi-agent configuration. As it is well-known, such issues have received increasing attention, as testified by the relevant number of contributions, see, e.g., [R1]–[R3] and references therein. Essentially, this is due to the success of using Unmanned Vehicles (UVs) in different areas of Industry 4.0 and Intelligent Transportation Systems, see, e.g., [R4]. In this context, it is important to underline that the design of a fully autonomous vehicle system must take into account the following key requirements: (i) each vehicle must be able to track a reference signal and reach the desired goal, (ii) formation control tools are needed to guarantee coordination among vehicles, and (iii) absence of collisions must be ensured.
Despite the significant interest, most of the existing approaches provide efficient solutions only when physical limitations are not taken into account in the vehicles’ modelling. As a consequence, their effectiveness and absence of collision claims are not guaranteed in real scenarios where the vehicle’s geometrical constraints and saturation effects play a crucial role.
According to these premises, the tutorial is devoted to disseminating recent advances in constrained control of multi-vehicle systems. We will discuss recent solutions addressing the collision-free reference tracking control problem for constrained multi-vehicle systems moving in shared environments (e.g. Industrial Plants and/or Cities) where obstacles might be present. The distinctiveness of this tutorial relies on showing that traditional Model Predictive Control (MPC) solutions can be combined with recent-developed Reinforcement Learning tools to derive novel and more efficient hybrid control architectures for multi-vehicle autonomous systems.
The tutorial will consist of four lectures. To encourage discussions, a Q&A period of 10/15 minutes will be available at the end of each part. Interaction between speakers and attendees will be strongly encouraged also during the talks.
Over the past recent years, the application of autonomous vehicles in different safety-critical domains, such as defence and space, search and rescue, health care, and industry 4.0, has gained increasing interest. Therefore, the research community has made a non-trivial effort to enlarge the applicability range of AVs within networked and distributed control setups. Accordingly, big corporations like Amazon, Google, and Tesla are carrying out their in-house research and prototyping AV solutions. The results of such actions are testified by the proliferation and diffusion of autonomous vehicles in both industry and society. Very popular examples of this phenomenon are the Tesla car (autonomous vehicle) and the Amazon warehouse robots (multi-vehicle systems). Therefore, this topic appears extremely relevant for its intrinsic interdisciplinary nature in both academia and industry contexts. The tutorial will help attendees to be familiar with the latest advances in the field and to open the doors to the next generation of control strategies for multi-agent vehicle systems.
A comprehensive set of slides covering all the background and topics material of the tutorial session will be carefully organized and provided to attendees.
