Abstract:In main active control schemes and inverse dynamic methods on vibration,there exist the problems of complicate in strategy and algorithm of control and difficult in real time control.In view of the facts that the robot manipulator is an extremely difficult,nonlinear,strong coupling complicate system,a study is made on the inverse dynamics and vibration inhibition of flexible manipulator.By applying principle of limit,an inversion method is presented for the joint and the optimal driving moment is obtained which will facilitate the inverse dynamic calculation.The study of the elastic vibration of robot manipulator centers on principle and strategy of its control.The proper position of the member is exerted so as to realize the control of the main modals of system deformation in different order.An effective method is obtained for inhibiting vibration of the system,with which the effect of structural flexibility on precision positioning can be remarkably reduced and the stability of the precision of the motion can be improved.
Keywords:flexible robot manipulator  inverse dynamic calculation  control of the precision of motion
