Further Improvement of Customized Vibration Generator for Machine–Human Feedbacks with the Help of Resonant Networks

Modern industrial, household and other equipment include sophisticated power mechanisms complicated control solutions require tighter human–machine–human interaction, forming the structures known as cyber–physical–human systems. Their significant parts are human–machine command links machine–human feedbacks. Such systems found in medicine, for example, orthopedics, where they important operation functional abilities of orthopedic devices—smart wheelchairs, verticalizers, prosthesis, rehabilitation units, etc. The mentioned feedbacks may be implemented based on haptic perceptions that vibration actuators. In such actuators can also used diagnostic purposes. This research brings forward idea use resonant driver actuator. corresponding has been built experimentally tested. It (1) point maximal current is actually defined by frequency, (2) change capacitance allows shifting output (3) damping factors make above-described effect less obvious. Further development proposed requires a comprehensive comparison four-quadrant two-quadrant schemes this application real-time programmable capacitor pack consisting several binary weighted capacitors commutating circuit, which installable to these schemes.
