    • This disclosure relates to a technique for smoothly carrying out an acceleration operation and a deceleration operation for a vibration type actuator to prevent a situation where in starting the vibration type actuator, a drive frequency is reduced to become lower than a resonance frequency to stop the vibration type actuator. A first counter performs up-count from a first value to a second value larger than the first value at predetermined time intervals in accelerating the vibration type actuator. A rate multiplier outputs a clock signal having a frequency corresponding to the count value. A second counter measures a period of a pulse signal, the period being adapted to change in correspondence to a drive speed of the vibration type actuator, by counting the clock pulses. The drive speed of the vibration type actuator is controlled such that the measured pulse period becomes a predetermined target value.
    • 本公开涉及一种用于平滑地执行振动型致动器的加速操作和减速操作的技术,以防止启动振动型致动器的情况,驱动频率降低到低于谐振频率以停止振动 型致动器。 在加速振动型致动器中,第一计数器以预定时间间隔从第一值到大于第一值的第二值执行增加计数。 速率倍增器输出具有对应于计数值的频率的时钟信号。 第二计数器通过对时钟脉冲进行计数来测量脉冲信号的周期,该周期适于与振动型致动器的驱动速度相对应地改变。 控制振动型致动器的驱动速度,使得测量的脉冲周期成为预定的目标值。

    • The present invention relates to a control device for vibration type actuator and, particularly, to an arrangement for forming a driving signal by using a pulse signal. In the invention, a periodic pulse is formed by integral multiplying of a period of a reference pulse, analog signals of first and second values are formed at each period of the periodic pulse, an analog signal of third value between the first and second values is formed in a short time, the analog signals are input to a low-pass filter so as to convert the signals to pulse signals by comparing the outputs of the low-pass filter with reference valves, and thereby the formed driving signal includes frequencies at higher resolution than that of the reference pulse so that the control device provides a drive with higher precision.
