Virtual Inertia as an Energy Dissipation Element for Haptic Interfaces [PDF]
IEEE Robotics and Automation Letters, 2022 Adding virtual damping to dissipate energy has been a major tool for designing stable haptic interfaces in most passivity-based approaches. However, virtual damping is known to dissipate a limited amount of energy. It even generates energy during high-velocity interaction because of the digitization effect, such as zero-order hold and quantization ...
