Abstract
PURPOSE: To enable an inexpensive proportional plus intergral controller to obtain high control precision by composing a proportional element of an analog circuit and an integral element of a digital circuit.
CONSTITUTION: This controller consists of reference input frequency-voltage converter 12 which converts reference pulse frequency fR into a direct-current voltage in proportion to it, feedback input frequency-voltage converter 14 which converts fed-back value fC, subtracter 16, proportional element 10 composed of summing amplifier 18, counter circuit 22 which integrates the deviation between reference pulse frequency fR and detection pulse frequency fC and makes a decision on the polarity of the integral value, digital-analog converter 24 which performs the voltage conversion of the output, integral element 20 composed of polarity addition circuit 26 adding a polarity to the output, and adder circuit 28 which adds together the outputs of those two elements.
