Abstract

PURPOSE:To realize an economical control system without excessively increasing the control power facilities, by increasing the time of application of a pulse type indication signal for control when the deviation obtained from the set value of the load is larger than the minimum reference deviation up to a prescribed frequency of detection. CONSTITUTION:The absolute value of a deviation Er to the set value of the load is larger than the absolute value Er0 of the minimum reference deviation from the 1st detection to a prescribed frequency of the detection, and the code is identical with each deviation Er. In such case, the application time (dts) having a minute time width is integrated to the basic application time (ts) of the pulse type indication signal that controls the load with every detection of the deviation Er and until a prescribed time point when the absolute value of the deviation Er is smaller than the value Er0 or the code becomes different from the original form. In case when a correction is given againt to the deviation Er next time and in the same direction, the total time (dts) is added to the application time (ts) of the first indication signal.
