chance properties. III. Optimum control in linear
systems. Minimum mean-square error

TEXT: The authors aim at determining an optimum control law for
linear stochastic control systems and analyze conditions, in which
a solution is possible. It is assumed that the automatic control
system is defined by a linear motion equation in terms of usual
coordinates, a variable4L(t) describing chance properties of the
system which is of a Mar.Kov character, and of a random pulse func-
tion representing interference. Transients are evaluated by a mi-
nimizing integral, and the problem is, therefore, that of finding
a control law which would ensure a probable asymptotic motion sta-
bility of X = 0. The method used is based on Lyapunov's optimal

mekhanika, v. 21, no. 4, 59 6, 1960 and v. 22, no, 4, 1961). The
method for approximate solution was previously described by the
authors, It is illustrated in the case of the system Aefined by a
linear motion equation. A parameter # is introduced-qt= 0 when
there are n independently controlled ohannelef and ~%-- 1 when only
one control affects all coordinates. When +-- 0, the optimal func-
