Realization of zero-power control in a two-degree-of-freedom double parallel magnetic suspension system

A basic single-degree-of-freedom magnetic suspension system consists of one floator, one electromagnet and one amplifier. For multi-degree-of-freedom control, multiple electromagnets and multiple amplifiers are necessary, which increases the cost of total system. As a means of overcoming this problem, parallel magnetic suspension has been proposed which controls multiple floators or multi-degree-of-freedom motions with a single power amplifier. This paper focuses on the zero-power control in a two-degree-of-freedom double parallel magnetic suspension system. The steady-state characteristics of this system are clarified by theoretical analysis. When the disturbance acts on one of the suspended points, a steady displacement appears only in the corresponding suspended point. The direction of the steady displacement is opposite to the direction of the disturbance. In addition, the direction of the transient response depends on the point that the disturbance acts on. In experimental apparatus, step response and frequency response are measured to verify the predictions.

Resonance frequency tracking control of ultrasonic transducer for diminished haptics

Previously, 'diminished haptics' in which real surface texture can be transformed was proposed. Strong intensity ultrasonic vibration was applied to realize demonstration of the concept. To enjoy the demonstration, the intensity of the ultrasonic vibration on solid surface should be maintained. The ultrasonic transducer fabricated for this purpose consisted of a Langevin type ultrasonic transducer and a horn whose end was shaped in square. Large vibration amplitude can be acquired at resonance of the whole transducer as longitudinal vibration mode. On the other hand, resonant frequency easily changes due to operating conditions. To keep the amplitude, the resonant frequency should be tracked by real time. Tracking control with phase detection was applied with a newly developed control system. Step responses of oscillating frequency as results of tracking control are reported. The results show successful tracking control.
