Necessary and sufficient conditions which lead to Pantryagin’s principle are stated and elaborated. 5. The present paper is concerned with a model class of linear stochastic Hamiltonian (LSH) systems [23] subject to random external forces. Similar to Hamiltonian mechan-ics in Ph ysics, the Hamiltonian for optimal control is dened based on a set of co-s tate variables obe ying an adjoint system of equations. (2009).
