Title: Digital servo apparatus
Inventor: KUNIHIRA TADASHI
IPC: H02P29/00
Filed: 1990-07-16
Abstract: PURPOSE:To set a rotating body to the preset velocity as quickly as possible by resetting a digital filter with highest acceleration of the rotating body with an output of phase control in the case where the rotating velocity does not reach a constant rotating velocity. CONSTITUTION:When a position detecting signal (d) is outputted from a position detecting means 6 at the time t1, a phase error calculating means 8 calculates phase error from the reference phase signal (e) and outputs it to a digital filter 9. Here, since the rotating velocity of a rotating body 1 is not within the predetermined range, namely since an output of a discriminating means 5 is 'L', an output of the digital filter 9 is fixed by an output control means 10 to '0' which is the highest acceleration output as shown by the signal waveform (g) and the digital filter 9 is reset. Accordingly, an output signal of a combining means 11 for combining the output signals (b) and (g) of a velocity error calculating means and digital filter 9 becomes '0' as shown by the signal waveform (h). As a result, a command signal to the drive means 12 becomes the highest acceleration signal and the rotating body 1 is most accelerated.

A spike voltage can be absorbed with a circuit consisting of the 1st and 2nd rectifier diodes 7, 10 and the capacitor 9. The charges of the capacitor 9 can be discharged to the power supply voltage with the circuit consisting of the resistor 8, a power supply 5, a capacitor 6, and the 4th rectifier diode 12.
