Abstract

PURPOSE: To promote a stabilization of the system, by changing a resistance ratio of the loop filter in accordance with a dividing ratio of the programmable counter that constitutes a phase locked loop (PLL), in a motor speed controller with PLL used.
CONSTITUTION: Rotational speed of a motor 5 is detected by a detector 6, being given to a phase comparator 2 through a programmable counter 7, and compared with a reference pulse generated from an oscillator 1. An output of the phase comparator 2, passing through a switch 10, a loop filter 3 and a servo amplifier 4, will construct a speed control signal for the motor 5. A resistor R1' is connected in parallel to a resistor R1 in the loop filter 3, with the switch 10 operated by an output of decoder 9, and a suitable selection of loop gain and damping factor will promote a stabilization of the system.
