ABSTRACT:
The paper presents a fuzzy logic speed control
system based on fuzzy logic approach for an indirect vector controlled induction
motor drive for high performance. The analysis, design and simulation of the
fuzzy logic controller for indirect vector control induction motor are carried
out based on fuzzy set theory. The proposed fuzzy controller is compared with
PI controller with no load and various load condition. The result demonstrates
the robustness and effectiveness of the proposed fuzzy controller for high
performance of induction motor drive system.

CONCLUSION:
This
paper has successfully demonstrated the application of the proposed fuzzy
sliding mode control system to an indirect field-oriented induction motor drive
for tracking periodic commands. First, the description of the classical sliding
mode controller (SMC) is presented in detail. Then, the fuzzy logic control is
used to mimic the hitting control law to remove the chattering. Compared with
the conventional sliding mode control system, the fuzzy sliding mode control
system results in robust control performance without chattering. The chattering
free improved performance of the FSMC makes it superior to conventional SMC,
and establishes its suitability for the induction motor drive.
