Weihai Chen, a professor at Beihang University's School of Automation Science and Electrical Engineering in Beijing and one of the coauthors of the paper, elaborated on the 2-DOF approach.
In this study, backlash effects on a 2-DOF robotic balancing table are investigated to provide feedbacks for the developers to create more accurate systems.
What distinguishes this work from the ones presented above is that the study focuses on a 2-DOF robotic balancing system plus backlash effects on motion.
In addition, the driver generally shows more concerns with the vehicle's lateral and yaw motion during the steering process [29], and a 2-DOF vehicle model is adopted as the internal model.
In this paper, it is assumed that the nonlinear characteristic of the 2-DOF vehicle model is mainly from the nonlinear tire performance, which is described by the UniTire model [33] as the Appendix.
To check the reliability of the viscoelastic (VE) model of the isolated structure in simulating the response under steady-state forced and following free vibrations, the isolated structure was idealized as a 2-DOF system, assuming the damping matrix as a linear combination of mass matrix and stiffness matrix with reference to the two vibration modes (Rayleigh damping).
Modelling the isolated structure as a 2-DOF system with VE behaviour (Rayleigh damping), the experimental displacement time-history (steady-state and free vibrations) was described with good accuracy for the isolation system, but it was underestimated for the superstructure due to the very low damping of the actual steel framed structure.
001) for the 2-DOF target postures (hook, opposition, and pointer) than for the 1-DOF target postures (palmar, tip, and lateral prehension).
developed a 2-DOF shoulder position transducer employing a load cell to sense shoulder motion of patients with quadriplegia in controlling powered wheelchairs [17].
In (Denzinger & Laureyns, 2008) a 2-DOF planar robot manipulator was presented.
The framework of the Transverse Assembly is composed of a U-shaped structure that surrounds the hand and forearm and functions as a 2-DOF wrist gimbal, where one of the two axes is aligned with the longitudinal axis of the forearm, component 8 in Figure 2(a), allowing pronosupination.
Frames 4-5 represent the 2-DOF of the elbow; frame 4 allows flexion/extension and frame 5 pronation/supination of the forearm.
