In the article approaches of direction of choice of criteria of optimumness of transformations and invariance are considered for the different situations of exploitation of the difficult control systems. Thus the result of the use of choice of criterion depends on the protuberant functions of losses, that enables to define the area of invariance for the difficult systems.
