โฆ Synopsis
A velocity and heading controller with integral control, designed using direct digital optimal control procedures and combined with guidance and trajectory algorithms to form an autoland system, achieved successful trajectory tracking when implemented on a CH-47 helicopter and flight tested along a descending-decelerating trajectory to hover.

We consider the classic Bellman and Zadeh multistage control problem under fuzzy constraints imposed on applied controls and fuzzy goals imposed on attained states with a stochastic system under control that is assumed to be a Markov chain. An optimal sequence of controls is sought that maximizes th
