Paper Title
Direct And Indirect Vector Control Of Induction Motors Using Hybrid Pid Plus Fuzzy Controller
Abstract
Speed control is one of the various application imposed constraints for the choice of a motor. For speed control of
a direct field-oriented induction motor (DFOIM) and indirect field-oriented induction motor, a Ziegler-Nichols (Z-N) based
PID plus fuzzy logic control (FLC) scheme is proposed in this paper. Theparameter values of Z-N PID can be chosen using a
simple and useful rule of thumb. The FLC is connected to the PID controller for enhancing robust performance in both
dynamic transient and steady-state periods. The FLC is developed based onthe output of the PID controller, and the output of
the FLC is thetorque command of the DFCIM. The complete closed-loop speedcontrol scheme is implemented in
MATLAB0.14-hpsquirrel-cage induction motor. Simulation results showthat the proposed Z-N PID+FLC scheme can lead
to desirablerobust speed tracking performance under load torque disturbances.Induction Motorperformance is checked
through the simulation studies inMATLAB/SIMULINK environment.
Keywords- Speed Control, Hybrid PID Plus Fuzzy Controller, Induction Motor, Ziegler-Nichols Method.
