Abstract:

A digitized version of the maximum principle is derived by a simple and elementary method. In the limit of the discrete time interval approaching zero, the digitized maximum principle is reduced to Pontryagins maximum principle. The digitized version can be readily programmed on a computer, and all four types of optimization problems 1 minimum time, 2 maximum range, 3 minimum cost between terminal points, and 4 maximum gain or minimum cost in a given interval, are solvable by this method. The computation of the optimum process requires relatively little computer memory, and is exact for systems describable by a set of difference equations. The use of a computer to implement the computed optimum process in various ways is discussed. A more general condition for bang-bang control is also derived. Author
