Abstract

PURPOSE: To realize the best response by preventing excessive integral operation by bringing negative feedback to the integrator of a PID control part to detect that an actuator has reached a saturation range.
CONSTITUTION: A speed signal from speed setter 1 and a signal from speed detector 2 are processed by comparing to generate deviation signal Δf and a signal obtained by adding this and output deviation signal Δp together is supplied to PID control part 3. Then, PID control part 3 performs proportional integral and differential processing of the input deviation signal to output an opening-degree command to actuator 5. Integral limiter 20 is supplied with the output of PID control part 3 and the difference of differential transformer 4 to provide negative feedback. The output of PID control part 3 is therefore controlled so that the deviation of actuator 5 from differential transformer 4 will not exceed the saturation value of actuator 5 much.
