%0 Journal Article %T An approximation to discrete optimal feedback controls %A Jinghao Zhu %A Zhiqiang Zou %J International Journal of Mathematics and Mathematical Sciences %D 2003 %I Hindawi Publishing Corporation %R 10.1155/s0161171203211042 %X We study discrete solutions of nonlinear optimal control problems. By value functions, we construct difference equations to approximate the optimal control on each interval of “small” time. We aim to find a discrete optimal feedback control. An algorithm is proposed for computing the solution of the optimal control problem. %U http://www.hindawi.com/journals/ijmms/2003/318587/abs/
