    • An improved self-oscillation system for a linear oscillatory actuator composed of a stator and a reciprocator. The stator carries a winding to which an electric current is periodically supplied for making a resonant oscillation of the reciprocator. The system includes a self-oscillation circuit for continuing the resonant oscillation of the actuator by a positive feedback manner based upon a back electromotive force (Vbemf) appearing across the winding. The system further includes a PWM control for increasing the electric current in response to a decreasing oscillation amplitude due to an increasing load applied to the reciprocator. A detector circuit is included to monitor the oscillation amplitude of the reciprocator and provides a corresponding detector output in response to which the self-oscillation circuit provides a drive pulse of varying pulse width for making the PWM control. The detector circuit is connected to monitor Vbemf of the winding in the absence of the electric current and to judge the instant oscillation amplitude of the reciprocator based upon the monitored Vbemf. Thus, the system can eliminate an external sensor, yet assuring the PMW control reliably based upon Vbemf correctly reflecting the actual oscillation of the reciprocator.
    • 一种用于由定子和往复运动器组成的线性振荡致动器的改进的自振荡系统。 定子承载周期性地提供电流的绕组,以进行往复运动器的共振振荡。 该系统包括一个自振荡电路,用于基于出现在绕组上的反电动势(Vbemf),通过正反馈方式继续致动器的谐振振荡。 该系统还包括一个PWM控制,用于响应由于施加到往复运动器的增加的负载而减小的振荡幅度来增加电流。 包括检测器电路以监视往复运动器的振荡幅度,并提供相应的检测器输出,响应于此,自振荡电路提供脉冲宽度变化的驱动脉冲用于进行PWM控制。 检测器电路在不存在电流的情况下连接到对绕组的Vbemf进行监测,并且基于所监视的Vbemf来判断往复运动器的瞬时振荡幅度。 因此,该系统可以消除外部传感器,而且基于正确反映往复运动器的实际振荡的Vbemf可靠地确保PMW控制。
