Linear, Nonlinear, Robust and Adaptive Control of a 3 DoF Cable Driven Parallel Robots

Dynamic analysis of cable robots is not the same as that of other parallel robots because cables can only pull an object but they cannot push. Therefore, the manipulator is able to perform a task only if the force in all cables are non-negative. Accordingly, the workspace of cable robots is defined as a region in space where the end-effector is able to exert the required wrench (force and moment vectors) to the surroundings while all cables are in tension (non-negative forces). Many research works have focused on workspace analysis and optimization of cable robots. Workspace and controllability of cable robots can be enhanced by adding cables to structure of the robot. Consequently, redundancy plays a key role in design of cable robots.
