Robust computationally efficient control of cooperative closed-chain manipulators with uncertain dynamics
This article presents a decentralized control scheme for the complex problem of simultaneous position and internal force control in cooperative multiple manipulator systems. The proposed controller is composed of a sliding mode control term and a force robustifying term to simultaneously control the payload’s position/orientation as well as the internal forces induced in the system. This is acc...
متن کاملRobust Control of Cooperative Manipulators
In this chapter we deal with the problem of robust position control for cooperative manipulators rigidly connected to an undeformable load. Design paradigms to solve force/position control problems have been established in the literature to improve the performance of the cooperation. In [8] a control strategy for cooperative manipulators was proposed based on the independence of the position an...
متن کاملRobust control of cooperative underactuated manipulators
We propose in this work the first model-based robust control method for a team of underactuated manipulators jointly manipulating a load. The method is based on feedback linearization of the nonlinear dynamic coupling between the torques applied at the actuated joints and the Cartesian acceleration of the load, combined with a variable structure controller. Singularities in the control method a...
متن کاملControl of Cooperative Manipulators with Passive Joints
The problem of the control of cooperative manipulators with passive joints and rigidly connected to a solid object is addressed in this paper. Passive joints can appear due to free-swinging joint failures or can be an intrinsic characteristic of the robots. A hybrid control of motion and squeeze force is proposed. For this purpose, a Jacobian matrix relating velocities in the actuated joints an...
متن کاملDynamics and Cooperative Object Manipulation Control of Suspended Mobile Manipulators
Dynamics and control of mobile manipulators is obviously a more challenging problem compared to fixed-base robots. Including a suspension system for these mobile platforms increases their maneuverability, but considerably adds to their complexity. In this paper, a suspended wheeled mobile platform with two 6-DOF Puma-type manipulators is used to manipulate an object along a given path. To apply...
