Title:
OUTPUT CONTROLLING DEVICE FOR GENERATOR
Document Type and Number:
Japanese Patent JPS5691699
Kind Code:
A
Abstract:
PURPOSE:To improve the responsiveness of the hunting phenomenon caused by an excessive controlling output and the insufficient follow-up and the like due to the shortage of the controlling output by a method wherein the pulse output is locked or released in proportion to the extent of the increment of a system deviation value. CONSTITUTION:A pulse oscillator 16 oscillates a pulse output 20 based on the deviation power DELTAP between a set output value 11 and a generated output value 12. The difference of the deviation power DELTAP is found by a deviator 17 and when the deviation power DELTAP is on the incremental direction, it is synchronized with the pulse oscillator 16, a lock pulse 21 is given to an adder 19 by the lock pulse oscillator 18, enabling a pulse output 14 to turn out. When the deviation power DELTAP is on the subtration direction, no pulse output is turned out. As a result, the control hunting can be prevented.
