The tasks of definition minimum number controlling action

For linear stationary system is solves the task of definition minimum number control action, by that open system may be make fully controlling. This result is allows to find all totality of systems control, by that is take place fully controlling and is possess by this minimum dimensions. As distinct from criteria Kalman's proposed approach is allows to consider the problem fully controlling another on stage of foundation controlling system. Moreover, offered approach is allows to appreciate excess of system control.
