This paper presents a novel vibration control technique for a pendulum via cable length manipulation. To control the sway angle by using the reeling and unreeling of the hositing cable. we develop a non-linear feedback control scheme by utilising parametric resonance. in which the control input is defined as the acceleration of the cable. https://www.ealisboa.com/quick-save-Pentair-Female-to-Female-Hose-Adapter-4-For-Sectional-Hose-K21241B-top-mega/
