Abstract : It is shown that every linear system with nondynamic feedback is optimal with respect to a quadratic performance index that includes a crossproduct term between the state and control. If the index is further generalized to include derivatives of the control, every (sufficiently smooth) linear, finitedimensional dynamic feedback and feedforward control system is optimal with respect to such an index. Methods of constructing all such indices are indicated, and some practical implications are discussed. (Author)
