Conserved- and zero-mean quadratic quantities in oscillatory systems

Rapisarda, Paolo and Willems, Jan C. (2005) Conserved- and zero-mean quadratic quantities in oscillatory systems Mathematics of Control, Signals, and Systems (MCSS), 17, (3), pp. 173-200.

Record type: Article


We study quadratic functionals of the variables of a linear oscillatory system and their derivatives. We show that such functionals are partitioned in conserved quantities and in trivially- and intrinsic zero-mean quantities. We also state an equipartition of energy principle for oscillatory systems.
