The step control problem depending on a parameter is investigated. Nonsmoothness of the cost function. is assumed and new versions of the discrete maximum principle for the step control problem are derived.Englishinfo:eu-repo/semantics/closedAccessoptimal control problems, subdifferential, superdifferential, maximum principle, step control systemOptimal Control ProblemsSubdifferentialSuperdifferentialStep Control SystemMaximum PrincipleOptimality Condition of a Nonsmooth Switching Control SystemArticle
