Active Compliance Control Based on EKF Torque Fusion for Robot Manipulators
RA-L 2023
To improve the accuracy of torque estimation and compliance control of the force sensorless, we propose a torque fusion method based on extended Kalman filter (EKF), both the data of motor current and the harmonic reducer torsional deformation are involved. First, a nonlinear EKF is designed based o
