Abstract:
This paper presents the comparison of applying an adaptive fuzzy controller with and without a variable structure controller (VSC) for a synchronous machine. A simplified linear model of the synchronous machine connected to an infinite bus with constant impedance is used. The multivariable system was previously decoupled to make easier the application of the control schemes. To control the system, an adaptive Fuzzy PD controller is proposed and it acts both on the load variable and on the voltage variable. Then, a Fuzzy Adaptive System is designed to act over the Fuzzy controller. After this, the VSC theory is applied to the Adaptive Controller to compare both strategies. Simulation results using these two control schemes are presented. With these proposed actions, the results show a better transitory response of the system when compared with the system response using classical control.
