【Abstract】 The equations of in-plane and out-of-plane motions of the tethered-payload system with driven belt having mass are derived by using the Newtonian law.Control is assumed to be provided only by modulating the driven force level in the drive mass as a function of the difference between actual and commanded position,position rate,in-plane swing angle and swing angle rate.Necessary and sufficient conditions for stability of the linear system motion in the vicinity of its nominal equilibrium position are developed.The experimental study of the in-plane controlled motion with friction complement is presented in detail.The effectiveness of the proposed control has been confirmed by the experiment.更多还原
