摘要： PURPOSE:To eliminate the unstableness of a servo system and to present the occurrence of noise by securing synchronism between the control of a positioning device done for fixed time and the detecting cycle of the absolute position of an absolute position detector. CONSTITUTION:The timing with which the present position of a movable stage 10 via an absolute position detector C is controlled accurately to a 2ms cycle by a real time clock RTC20. Thus the interruption signal S2 to be applied to an MPU1 is also set accurately at 2ms and the control timing with which the MPU1 calculates the following deviation and outputs the speed signal S1 is set accurately at 2ms. This control timing has a delay just by a constant time to the detection timing. Therefore the follow-up deviation is fixed when the interpolated control target value has its change at a fixed speed. Thus the speed of the stage 10 is also fixed and therefore the unstableness of a servo system is improved.

摘要： PURPOSE:To improve control performance while enhancing the resolving power of the detection of a position by mounting a phase compensating circuit compensating the phase of a commutation signal. CONSTITUTION:A phase compensating circuit 13 outputs phase compensating signals Va-Vc compensating the phase of commutation signals CSa-CSc on the basis of a speed detecting signal etg and current detecting signals iao-ico. Consequently, the phase of the commutation signals is compensated collectively by the compensation of the phase of the commutation signals CSa-CSc by the phase compensating signals Va-Vc. Accordingly, the effect of various phase lags is compensated extending over the whole speed range to high speed from low speed of a brushless motor.

摘要： PURPOSE:To reduce a higher harmonic containing rate in a low dimension increasing a frequency of a trangular wave by the adjustment of an oscillator by a method wherein rectangular wave outputs from the oscillator are integrated by a triangular wave generator to obtain the triangular wave, and the inverter is driven by comparing the triangular wave with an output of a sine-wave generator. CONSTITUTION:A supply unit of call signals for telephone is formed of an inverter circuit 21, a filter 22 and a control circuit 1. The control circuit 1 supplies the rectangular wave voltage of the oscillator 6 to a comparator 9 through a triangular wave generating circuit 7 and also, supplies the rectangular wave voltage to the comparator 9 through the sine-wave generator 8 comprising a counter circuit 14, a memory circuit 15, a D/A converter 16 and a polarity converter 17, and driving signals of a pulse width modulation type are fed to the inverter 21 by the output of the comparator. Accordingly, the frequency of the triangular wave can be turned to a high frequency by adiusting the oscillator 6, and the higher harmonic containing rate in a low dimension is decreased to make the filter 22 be small-size.

摘要： PROBLEM TO BE SOLVED: To increase the frequency accuracy of a power supply, after frequency tracking by varying a frequency division value of a variable frequency divider through interrupt processing of a CPU by rising and falling of a commercial power supply and of a counter to allow a sine wave output circuit to track a frequency of the power supply. SOLUTION: In the interrupt processing of a CPU by rising and falling of a commercial power supply, a frequency division value of a variable frequency divider 72 is decreased, and in the interrupt processing by a counter 5, the frequency division value of the variable frequency divider 72 is increased. When the frequency of the commercial power supply 1 becomes lower, the variable frequency divider 72 increases its frequency division ratio, to reduce a frequency of a sine wave output of a sine wave generating circuit 8. When the frequency of the commercial power supply 1 becomes higher, the variable frequency divider 72 decreases its frequency division ratio, to increase the frequency of the sine wave output of the sine wave generating circuit 8. As a result, the sine wave output frequency of the sine wave generating circuit 8 traces the frequency of the commercial power supply 1.
