  • Abstract
    We consider singular optimal control problems consisting of a state equation \\dot{x}=Ax+bu for vectors x and scalars u and a cost functional J = frac{1}{2} \\int\\min{0}\\max {T}(x\´Qx+\\epsilon^{2}u^{2})dt to be minimized for |u|\\leq m and \\epsilon=0 . By considering the problem as \\epsilon \\rightarrow 0 , singular perturbation concepts can be used to compute solutions consisting of bang-bang controls followed by singular arcs. The procedure further develops a numerical technique proposed by Jacobson, Gershwin, and Lele [18], as well as additional analytic methods developed by other authors.
