A Robust Hybrid Position/Force Control Considering Motor Torque Saturation
2021
IEEE Access
Preserved Fulltext
This paper proposes a robust hybrid position/force control (HPFC) system for multi-degree of freedom manipulators (MDoFMs) with torque constraints on each joint. ...
Consequently, the stability and robustness of the actuators are considered, and suitable position/force control can be performed even if the torque is saturated. ...
INTRODUCTION Hybrid position/force control (HPFC) [1] , [2] is a control method for the positions and forces of multi-degree of freedom manipulators (MDoFM), by which it is possible to control the position ...
