Abstract

PURPOSE:To obtain the same controllability by a simple constitution as same as a method using phase control loop system by increasing the stability through application of a crystal oscillator's frequency as a reference frequency and inserting an integration circuit in a speed control loop. CONSTITUTION:The signal from a tachogenerator 2 and the signal from a reference frequency signal generation circuit 4 including the crystal oscillator are inputted to a rotary speed processing circuit 5 consisting of constant pulse width generating circuits 6, 7 and a pulse synthesizing circuit 8 centering around a counter. Its output is, through integration, supplied to a phase information synthesizing circuit 9 which generates a phase information for an electic motor 1 and a damping information synthesizing circuit 10 by eliminating high-frequency component and D/C component for the electric motor 1. Then both signals are added, to control the electric motor 1. Consequently, despite simple constitution, it is possible to obtain the same control characteristic as speed control apparatus which concurrently uses a phase control loop and a speed control loop.
