Wu, Limeng; Ni, Mingkang Internal layer solutions of singularly perturbed optimal control problems. (Chinese. English summary) Zbl 1274.49004 Acta Phys. Sin. 61, No. 8, 080203 (2012). Summary: A class of singularly perturbed optimal control problems are studied by a direct scheme method, which is based on the boundary function method. The internal layer solution is proved to be existing, and the uniformly valid asymptotic solutions for the singularly perturbed optimal control problems are constructed.
