Detailed Documentation
This Simulink model implements the selective harmonic elimination (SHE) method for induction motor control systems. The method enhances motor performance by strategically eliminating specific harmonic components in the motor's current and voltage waveforms. Harmonics represent a prevalent issue in power systems that can cause grid instability and equipment damage. The model incorporates PWM signal generation algorithms that compute optimal switching angles to cancel targeted harmonics while maintaining fundamental frequency components. Key Simulink blocks include harmonic calculation modules, switching pattern generators, and motor dynamic simulation components. This implementation helps engineers better understand and apply SHE techniques through visual simulation of harmonic spectrum analysis and real-time performance monitoring, ultimately improving induction motor efficiency and operational reliability.
