On a problem of optimal speed.
Management of a second-order object is considered under control restriction. It is shown that this task can be reduced to a second-order object control problem with coordinate constraint. Optimal control of an n-th order control object with (n-2) asgatism order under control constraint is considered. that this task can also be reduced to a problem of controlling an object of the second order with coordinate constraints. The solution of the problem with respect to the electric drive is considered.
