Abstract:
The aim of this paper is to develop a suitable control of Multi-Body Cable-Driven Robot with satisfactory tensionnability condition. The desired trajectory is given in joint mobile platform space and thereby transformed on joint actuator space using the developed inverse kinematic. Under the control scheme, the actuator joint coordinates obtained by the sensor are used as feedback for the control system. Adding to the error in joint actuator space, the cable tensions which are computed based on the mobile platform dynamic and the optimization problem are used as inputs of the controller. The sliding mode control method based on linear reaching law is used to control the effector of the robot. Asymptotic stability of the closed loop system is analyzed through Lyapunov theorem. Finally, a motion tracking based on the proposed control strategy is carried out on the Multi Body Cable-Driven Robot. The obtained results show the effectiveness and the feasiblity of the proposed control method.
