This paper provides a detailed examination of speed control methods for induction motors, with a specific focus on the use of different pulse width modulation (PWM) techniques to achieve precise speed regulation and efficient motor operation. The study investigates the application of sinusoidal PWM (SPWM), third harmonic injection PWM (THPWM), space vector PWM (SVPWM), and selective harmonic elimination PWM (SHEPWM). The proposed hybrid PWM technique is analyzed and compared with existing PWM techniques in both open-loop and closed-loop control strategies. The incorporation of feedback mechanisms such as speed sensors to dynamically adjust the PWM signals has been considered. Through the adjustment of carrier signal frequency and modulation index, the study identifies the optimal PWM technique for minimizing total harmonic distortion (THD) and switching losses. The paper concludes with recommendations on the most effective PWM techniques for specific conditions.
