Passivity-based approaches to bilateral teleoperation sacrifice performance to achieve robust stability against time-varying delays. Typically, force and velocity signals are exchanged in passivity-based bilateral teleoperation resulting in good velocity tracking, but may accrue a position drift. Recently, a power-based time domain passivity approach (TDPA) was proposed to passivate the communication...
In this paper, the power and energy behavior of bilateral communication with time delay is analyzed. Time delay may result in activeness and in turn generate energy. In a bilateral system, the energy generated by time delay communication can destabilize the whole system. Based on the power based time domain passivity control previously proposed by the authors, a time domain passivity control approach...
Any teleoperation system involving two distant devices is affected by communication delay due to the physical gap between the devices. Several approaches based on wave variables have already been proposed to deal with time-varying delay. However, these approaches are too conservative resulting in high degradation from the constant time delay case. In this paper, we propose a new control scheme for...
