By the terms barrier, potential and antiobject first so-called geometrically justified splash phenomenon of phase coordinates in control of dynamic systems. A solution of the prediction amplitudes controls any dynamical system with known control laws with a unified position theory of linear systems is represented. Created identity module and experimental determination of a geometric average root (GAR) for any complexity dynamical systems in real time. 3 number of geometric means , and is determine a solution to any problem in the control theory. Appropriate to talk about a measure of "energy charge" for slave/master: trajectory tracking and reference model , the dynamic objects as such, and a closed system as a whole at various GAR , like orbits in the Bohr model of the atom. The fact of non-arising splash the basis for an evaluation criterion robustness of systems and strategies for quality control of dynamic systems. Ratio as a rapid-test can become a reliable indicator of the feasibility of the known control laws. Potentially, the score coefficients by any other non-modal methods, only will notify about the presence/absence of a splash. Sure, appropriate to willfully pointwise predetermine GAR, otherwise simply unattainable.
