RT journal article T1 Robust penalty function method for an uncertain multi-time control optimization problems A1 Jayswal, Anurag A1 Preeti A1 Arana Jiménez, Manuel A2 Estadística e Investigación Operativa K1 Absolute value penalty function method K1 Convexity Multi-time control optimization problem K1 Robust necessary optimality conditions K1 Robust optimal solution AB This paper gives some new results on multi-time first-order PDE constrained control optimization problem in the face of data uncertainty (MCOPU). We obtain the robust sufficient optimality conditions for (MCOPU). Further, we construct an unconstrained multi-time control optimization problem (MCOPU) corresponding to (MCOPU) via absolute value penalty function method. Then, we show that the robust optimal solution to the constrained problem and a robust minimizer to the unconstrained problem are equivalent under suitable hypotheses. Moreover, we give some non-trivial examples to validate the results established in this paper PB Elsevier SN 1096-0813 YR 2022 FD 2022-01-01 LK http://hdl.handle.net/10498/40417 UL http://hdl.handle.net/10498/40417 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 06-nov-2026
