Through the research about measurement and control system of alternating current net amplitude, the error was eliminated by using incremental digital PI with integral after the amplification of dispersion absolute value. Simulation results show that the designed system can measure the alternating current net amplitude exactly,and can estimate whether the pressure of alternating current net is normal according to integrator sendout,and have good interference immunity and dynamic.
