Abstract — Vector Control Induction Motor MATLAB

impact of these harmonics and presents a solution by implementing a low-pass filter to achieve a cleaner, more sinusoidal current waveform[cite: 1889]. The simulation model was used to analyze the system's performance. The key results are highlighted in the waveforms below: Rotor Speed: The motor's rotor speed successfully stabilizes at the desired setpoint after an initial transient period, demonstrating effective closed-loop control.

Analytical & State-Space Control Methodology

Chapter 2: Semiconductor Dynamics: MOSFET & IGBT Switching Characteristics & Losses Stator Current (Without Filter): The unfiltered stator current is nearly sinusoidal but exhibits significant high-frequency harmonic distortion.

Simulink Waveforms & Power Quality Findings

Stator Current (With Filter): After applying the low-pass filter, the stator current waveform is much smoother, more closely resembling a pure sine wave. [cite_start]This leads to improved motor efficiency and reduced stress[cite: 1764]. While effective, the SPWM technique has limitations. [cite_start]Future research could explore more advanced modulation techniques to further improve performance[cite: 1897]: A MATLAB/Simulink project for a closed-loop induction motor drive using SPWM control. It demonstrates harmonic mitigation in the stator current via a low-pass filter to boost overall motor efficiency and operational stability.
