On Control of Twolink Robotic Manipulator on the Base of Picontroller
The article deals with the problem of of twolink robotic manipulator program motions stabilization on a movable base by creating a PIcontroller. The manipulator consists of two homogeneous links connected by a joint. A moving load is placed in the second link gripper. A movable base makes a translational motion in the horizontal plane. The links of the manipulator are also moving in the horizontal plane. Thus, the manipulator performs planar motion. The manipulator motions are described by the system of Lagrange equations of the second kind. The paper presents a control law carrying out stabilization of the given program motion as a proportionalintegral dependence on condition that the base of the manipulator performs predetermined unsteady motion. The problem of program motion stabilization has been solved for the linearized model. For the numerical simulation a new program that allows providing PIcontrol for the various mechanical systems was used. A numerical solution of the resulting system of integraldifferential equations is found. A numerical solution of the received system of integraldifferential equations with abnormal indices is found. The corresponding graphs for the coordinates of the manipulator links proving the theoretical results are built. Twolink manipulator, stabilization, program motion, picontrol, movable base.
