xvi 1 Optimal Control Theory 1 1.

We consider a vibrating string that is fixed at one end with Neumann control action at the other end. We investigate the optimal control problem of steering this system from given initial data to rest, in time T , by minimizing an objective functional that is the convex sum of the L-norm of the control and of a boundary Neumann tracking term. We provide an explicit solution of this optimal cont...

This paper presents simple sufficient conditions under which optimal bunches in adverse-selection principal-agent problems can be characterized without using optimal control theory.

We introduce the idea of boundary extremals (3.9) in control problems for simple fluid models of queueing systems with Skorokohd dynamics, using the robust formulation of [2, 4]. A simple example is presented in which these extremals play a fundamental role in the construction of the optimal control strategy.

most of authors (1-7) have used discontinious methods based on trial and error procedures for determination of optimum distribution of kh and ?h. optimal control theory has not been used for gas reservoirs. hence, in this paper optimal control theory is utilized for mathematical simulation of gas reservoir and optimum distributions of kh and ?h are presented. one of themain advantages of this n...

The objective of the present research is to make use of optimal control theory to solve a serious environment and transportation problem.
