  • Abstract
    Linear control processes are considered under the following optimization criteria: 1) minimization of the terminal error and 2) minimization of the required time ( T ) to reach a desirable state. The constraint on the control vector (u(t)) is considered to be \\int\\liminf {t_{j}} \\limsup {t_{j+1}} u\´(t)Qu(t)dt \\leq c_{j} j = 1, 2, ... m where Q is a positive definite matrix, and t_{j} < t < t_{j+1} represents any given interval contained in the interval 0< t< T , and cjcan be considered as the available energy during that interval. A condition of optimality has been obtained which can be used analytically. Furthermore, a numerical procedure is developed for determination of the optimum control vector.
