Recently, research and development on non-contacting control technology utilizing acoustic radiation pressure (ARP) has been performed. Watanabe had presented a direct control mechanism of ARP by modulating the oscillating current that excites the ultrasonic vibrator. In this research, am electronic control system is introduced to realize ARP control. Moreover, experimental ARP measurement system is developed to measure ARP precisely. Using these systems, the dynamics of the entire ARP control system is identified. Meanwhile, non-contact experiments are carried out. A simple pendulum is adopted as a control object. Two welders are located symmetrically with the direction of oscillation. Control results showed good control performance. These facts indicated the effectiveness of the presented ARP control system for non-contacting control.
