Abstract

The dynamic performance of a linear oscillatory actuator (LOA) is computed using the finite element method, when it is operated by feedback control. In this computation, the magnetic field is perfectly coupled with the driving electric circuit and the kinetic motion of the mover. Comparison with the measured results verifies the validity of this analysis. The influence of feedback control function on the mover amplitude is also verified. In addition, the method of feedback control using the signal, obtained by the induced voltage from a sensing coil in place of a optical sensor is investigated. As a result of that, it is found that both control methods produce almost the same performance
