Abstract
In this thesis hybrid Fuzzy-PI control speed control of five-phase induction motor vector control
is modeled. For modeling purpose five phase squirrel-cage induction motor is selected. This
selected motor is analyzed on d-q synchronously rotating reference frame. Also third and fifth
harmonics did not considered & fundamental harmonics is taken in to consideration.
In this thesis hybridization technique is applied by connecting both Fuzzy and PI controllers in
parallel, giving a common error for both of them from speed comparator output.
The operation sequence first starts from FLC. Then, FLC tunes constants of PI ( & ), then PI
controller produces command torque depending on values of ( & ) tuned by FLC.
Simulation output results show that the transient response of Fuzzy-PI is better than that of PI
transient performances. For this work Matlab/Simulink is used in modeling and verification of
models performances.
