Using sensorless direct torque with fuzzy proportional-integral controller to control three phase induction motor

Induction motors (IM) attracted many researchers in the last few decades. In this field, various applications are implemented, such as servo motor drives and electric vehicles. This work applies a sensorless direct torque controller (DTC) to control three-phase IM. System dynamics of IM were derived. A nonlinear dynamic model had introduced with white noise. Given complexity dynamics, Jacobean Linearization technique has been used obtain linear for task. DTC is employed speed system combination two controllers. The fuzzy proportional-integral (PI) controllers applied reference based on an optimization process against error raise. optimizer called grey wolf (GWO) implemented achieve centre values output memberships PI Then extended Kalman filter (EKF) evaluate quadratic components rotor flux from observation stator voltages currents. tested employing MATLAB simulation software determines targeted results. outcomes evaluated improve performance.
