Abstract
PURPOSE: To keep detection accuracy and trasient response good through a simple construction, by compensating the analogue voltage signal of a pilot electricity generator by the pulse signal of a pulse oscillator.
CONSTITUTION: An adder subtracter 4, a signal converter 3 and an integrator 6 are provided. The adder subtracter 4 compensates the analogue voltage signal of a pilot electricity generator 1 by an analogue error signal to supply a speed detection signal as an output. The signal converter 3 changes the pulse signal of a pulse oscilltor 2 into an analogue voltage signal proportional to the frequency of the pulse signal. The integrator 6 integrates the difference between the output signals of the signal converter and the adder subtracter to supply an analogue error signal as an output. When the analogue voltage signal of the pilot electricity generator 1 has an error, an integrated error value appears on the output of the integrator 6 and a polarity converter 5 performs polarity conversion to supply an analogue error signal to the adder subtracter 4 to correct the error of the analogue voltage signal. Detection accuracy and transient response can thus be kept good by simple constitution.
