Control Systems In the integral control of the single area system frequency error is reduced to zero. Then integrator o/p increases but speed changer position comes down. integrator o/p decreases but speed changer position moves up. integrator o/p decreases and speed changer position comes down. integrator output and speed changer position attain a constant value. integrator o/p increases but speed changer position comes down. integrator o/p decreases but speed changer position moves up. integrator o/p decreases and speed changer position comes down. integrator output and speed changer position attain a constant value.
