Abstract

The paper promotes a relatively novel class of multi-agent control systems named “impulsive” continuity equations. Systems of this sort, describing the dynamics of probabilistically distributed “crowd” of homotypic individuals, are intensively studied in the case when the driving vector field is bounded and sufficiently regular. We, instead, consider the case when the vector field is unbounded, namely, affine in a control parameter, which is only integrally constrained. This means that the “crowd” can be influenced by “shock” impacts, i.e., actions of small duration but very high intensity. For such control continuity equations, we design an impulsive relaxation by closing the set of solutions in a suitable coarse topology. The main result presents a constructive form of the relaxed system. A connection of the obtained results to problems of contact dynamics is also discussed along with applications to optimal ensemble control and other promising issues.

The restoration law represents a mechanical specification of the obstacle (in our interpretation, of the “curb”) due to concrete properties of its material; we deal with an “idealized”, academic model. Recall that, in general, the intensity of impact depends on mechanical properties of colliding objects, and restoration laws can be different, depending on the law of interaction [24]. Practically, computation of the actual restoration law is a complicated problem with a number of pitfalls such as the famous Painlevé paradox [22].
