Control and Systems Engineering discusses a master's thesis on the design of a multi-level space vector pulse modulation inverter for sensorless control of a synchronous motor
The thesis of postgraduate student Roaa Sabah Hasan, majoring in control engineering, aimed to use permanent magnet synchronous motors widely in the industry because of their excellent efficiency, low power/weight ratio and smooth torque. Vector control technology is used to control the speed of the motor in relation to the required speed range. Field orientation control strategy is the complex strategy of control but gives smooth response To reduce the harmonics at the inverter output voltage, PWM/Multi-level technology was used. SVPWM technology is better than sinusoidal PWM technology, as this technology has been used in two and three levels This thesis proposes a non-sensing estimation of the speed of a transmission-controlled synchronous motor using a modular adaptive reference system MRAS Due to its performance and uncomplicated stability approach, MRAS-based procedures are one of the best methods for estimating rotor speed Also, a whale optimization algorithm was used to adjust the controller, as this algorithm showed good performance of the system.
The discussion committee consisted of Prof. DR. Abbas Hussein Issa, Chairman and membership of each of Dr. Basim Ghaleb Mojbel and . Dr. Yasser Nabil Ibrahim and supervised by Dr. Farazdaq Rafiq Yassin.
