Abstract
A swinging person has been known to be able to control sway oscillations by the periodic variation of system parameter that is the effective pendulum length. It follows from Sect. 10.3 that the operator can vary not only the parameter variation amplitude but also the variation phase; thereby, the excitation and damping of the parametric swing oscillations are affected. This is the manual parametric control.
