Discrete approximations of a controlled sweeping process. (English) Zbl 1312.49015
Summary: The paper is devoted to the study of a new class of optimal control problems governed by the classical Moreau sweeping process with the new feature that the polyhedral moving set is not fixed while controlled by time-dependent functions. The dynamics of such problems are described by dissipative non-Lipschitzian differential inclusions with state constraints of equality and inequality types. It makes their analysis and optimization challenging and difficult. In this paper we establish some existence results for the sweeping process under consideration and develop the method of discrete approximations that allows us to strongly approximate, in the \(W^{1,2}\) topology, optimal solutions of the continuous-type sweeping process by their discrete counterparts.
