Abstract
This work discusses the simulation and experimental demonstration of a genetic algorithm hybrid fuzzy-fuzzy controller (GA-HFFC) system to achieve speed control of a variable-speed induction motor (IM) drive based on a space vector pulse width modulation (SVPWM) technique by means of an eZdspF28335 digital signal processing (DSP) experiment board. Two features of field-oriented control (FOC) were used to design the GA-HFFC, namely, the current and frequency. To overcome the limitations of the FOC technique, the principles of the GA-HFFC were introduced through the acceleration-deceleration stages to regulate the speed of the rotor with the help of a fuzzy frequency controller, while a fuzzy stator current amplitude controller was involved during the steady-state stage. The results revealed that the proposed control approach could deliver a practical control solution in the presence of diverse operating conditions.

This study investigates the resilience of induction motor control drive systems that use genetic algorithm hybrid fuzzy-fuzzy controller (GA-hybrid fuzzy-fuzzy controller (HFFC)) three-phase squirrel-cage induction motor (SCIM) drives to overcome the shortcomings of vector control
The objective of this research is to demonstrate a practical implementation of the proposed genetic algorithms (GAs)-HFFC system to control an induction motor (IM) based on the space vector pulse width modulation (SVPWM) technique in digital signal processing (DSP)
Summary
I N industrial applications, induction motors are well known for their reliability, minimal maintenance and low cost. Modern high-performance electrical drives are characterized by small steady-state errors, resilience to system parameter fluctuations, direct and fail-safe control algorithms, quick transient response, small overshoots, wide operating ranges, low maintenance, and low-cost applications [17] Due to their low cost and durable design, induction motors are the backbone of the industry. The objective of this research is to demonstrate a practical implementation of the proposed GA-HFFC system to control an induction motor (IM) based on the space vector pulse width modulation (SVPWM) technique in digital signal processing (DSP) To fulfill this objective, an incremental encoder was joined to the motor shaft, and Hall effect current sensors were used to identify the direct currents to the motor with the designed auxiliary circuits. The second feature is satisfied by the fact that (4) remains constant if the torque command T ∗ is kept constant
