3DOF-PID Controllers Based DTC of Five Phase Induction Motor Drive

The growing interest in five phase induction motors can be attributed to their diverse range of applications, which encompass electric vehicles, advanced compressor systems, and marine propulsion, among others. A proper control methodology must be implemented to operate drive at its highest performance level. Among many, Direct Torque Control (DTC) methodology is developed for various tasks. However DTC with conventional PI/PID controllers are unfit to exhibits its best performance under critical conditions. Hence, Three Degree of Freedom Proportional-Integral-Derivative (3DOF-PID) controller is utilized in the proposed DTC methodology. Additionally, 3DOF-PID controllers are capable of delivering a swift response to rapid input variations. Consequently, this paper proposes a 3DOF-PID controller based DTC for a five phase induction motor. Additionally, the space vector pulse width modulation (SVPWM) technique is employed to generate the appropriate pulse sequence for a five leg inverter used in motor drive applications. A detailed design of 3DOF-PID controller is also incorporated in this paper. In addition to this, Whale Inspired Algorithm (WIA) is developed to tune various parameters of 3DOF-PID controller. In order to make speed sensorless controller, mathematical modeling is included to estimate speed of the motor to avoid physical sensor. Hardware - in the - Loop (HIL) technique is implemented on OPAL-RT platform to present various results similar to real time responses.
