Abstract
Power system stabilization has been, and still is, a major interest of rese archers in the area of power systems, Recently, modern control techniques b ased on ar artificial intelligence, like artificial neural networks and fuz zy logic, presented elegant and neat solutions for power system stabilizati on; however, some of these techniques face resistance of the control engine ers who are not yet famil iar with artificial intelligence. This paper intr oduces a hybrid fuzzy PID power system stabilizer (FPID) that retains the n ature of the conventional PID controller and enhances its performance using fuzzy logic. The fuzzy logic provides on-line automatic adjustment of the PID parameters. Tuning of initial FPID parameters is similar to that of a c onventional PID controller. The proposed controller proves, through extensi ve simulation tests for different machine operating points and under differ ent disturbances, that it outperforms techniques based on either convention al PID or conventional fuzzy logic controller (FLC).
