TITLE: One of the problems of optimal control
SOURCEs Leningrad. Universitst. Vestaik. Seriya matematiki, makhaniki i as-
tronomii. no. 1, 1964, 7 " 7.
TOPIC TAGS: space exploration. applied mathematics. satellite orbit, automatic
control, high speed control, Poutryagin maxi
ABSTRACT: This analysis of the problems of optimal control uses the Pontryagin
maxi== principle to 'ptove a theorem similar to th6 on6 an the finiteness of the
number of changes in linear optizial variations. A second order equation with two
controlled parameters is investigated in detail. An example is given shoving
that in optimal control problems, variable optimal control is possible. The pro-
blem of optisial high-speed control of an object, the motion of which is described
by the equation:

is considered. Orig. art. has: 3 figures.

ty of interior points of this set decomposes into regions of I'dy-
