Title:
MATCHING SPEED CONTROLLER OF DC ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS59144386
Kind Code:
A
Abstract:
PURPOSE:To obtain the followup accuracy rapid by 5-10 times in case of matching speed by using a speed control amplifier output signal in a speed control major loop of a master motor side as a current control command in the major loop of a slave motor side. CONSTITUTION:A comparator 9' of a slave motor side produces a deviation signal by comparing the output signal I7' of its speed control amplifier 7', similarly a detected current I1' from a current transformer 8' and further an output command signal I7 from a master motor side speed control amplifier 7, and supplies a reference signal of constant current to a current control amplifier 10'. The responding time of the minor loop of the current control is faster by 5-10 times than that of the speed control major loop, and the followup accuracy faster by 5-10 times than the major loop can be obtained.
