Minimax decisions in some problems of control with many sources of disturbances

In the paper, a stochastic system with many sources of disturbances is considered. These disturbances have distributions belonging to the exponential family with some unknown parameters. Moreover, it is assumed that a control is disturbed too. A horizon of control is a random variable with a known distribution. Under some additional assumptions the problem of Bayes and minimax control of such system is solved.
