Investigation of problem of providing automatic control system for large booster subject to severe mode interaction revealed that active control philosophy using auxiliary control inputs to increase frequencies of elastic modes sufficient to reduce mode interaction in forward-loop is false notion; it is free-free bending modes which interact with rigid-body motion, and input forces cannot alter their mode shapes and frequencies; they can be altered only by mass and structural stiffness changes to basic vehicles; summary of conclusions.
