B. AC Voltage Regulator Controller VII. MODELING AND SIMULATION

The membership functions of the error signal consists of 5 Simulation has been carried out under different loads con-
linguistic variables as shown in Fig. 9. For change of error ditions using the design in Fig. 12 which based on control
there are 3 linguistic variables as obvious in Fig. 10. For systems shown in Fig. 13 and Fig. 14. Filters with an inductor
output signal there are 7 linguistic variables as shown in Fig. of 25mH and a capacitor of 110uf have been chosen according
11. The rules linking between input(error and change of error) to the basic formula of the filter design [18]:
and output signals of the ac voltage controller is demonstrated
in Table III.
