Optimal Control Theory

Optimum regulate idea is the technological know-how of maximizing the returns from and minimizing the prices of the operation of actual, social, and financial tactics. aimed toward upper-level undergraduates, this article introduces 3 points of optimum regulate conception: dynamic programming, Pontryagin's minimal precept, and numerical concepts for trajectory optimization.

Principles of Optimal Control Theory, 1st Edition

Within the past due 1950's, the gang of Soviet mathematicians together with L. S. Pontryagin, V. G. Boltyanskii, R. V. Gamkrelidze, and E. F. Mishchenko made primary contributions to optimum regulate idea. a lot in their paintings used to be accrued of their monograph, The Mathematical conception of optimum techniques.
