摘要： 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.

摘要： A vibration type activator having improved electro-mechanical energy conversion efficiency and reduced noise generation includes plural switching elements each of which is operated by a switching pulse signal generated by a drive control circuit of the motor. A drive control circuit selects a pulse width of the generated switching pulse signal such that the amplitude of a base wave frequency component (“base wave”) among frequency components of a voltage applied to an inductance element may be larger than a total amplitude of higher harmonic wave frequency components (“whole higher harmonic wave”).

摘要： This invention relates to a driving device for a vibration type actuator. In this device, since the characteristics of the actuator change depending on temperature and the like, control characteristics must be optimized. This invention is designed to determine a control gain based on the ratio of the change amount of the frequency of a driving signal that causes the speed change to the change amount of the speed when the driving speed changes a predetermined amount upon driving of the actuator, thereby performing appropriate control.

摘要： This invention relates to an apparatus for simultaneously driving a plurality of vibration type motors. The frequency of a cyclic signal at which the motors exhibit the same speed is detected from the driving characteristics obtained upon application of the cyclic signal to each motor. When the motors are simultaneously driven, a cyclic signal having the detected frequency for each motor is applied to each motor to make the speeds of the motors equal to each other.
