MATLAB Simulation of Three-Phase Three-Wire Active Power Filter with Integrated Position Tracking Sliding Mode Control

This MATLAB Simulink model implements a three-phase three-wire active power filter simulation featuring an integral-based position tracking sliding mode control strategy for accurate source current tracking. The model includes power electronics components like IGBT inverters and current sensors to replicate real-world APF operation.

In this simulation model, we conduct research using a three-phase three-wire active power filter configuration. The filter effectively eliminates harmonics and noise from the power supply, ensuring clean and stable source current. The control algorithm employs sliding mode control with integral action for position tracking, which continuously adjusts the power current output through PWM signal generation to maintain consistency with reference signals. Key implemented functions include harmonic detection using instantaneous power theory and DC-link voltage regulation. This tracking control approach enhances system stability and response speed, ultimately improving overall system performance and efficiency through reduced THD (Total Harmonic Distortion).

Through this MATLAB simulation model, researchers can effectively study and understand source current tracking control methodologies for three-phase three-wire active power filters. The model provides valuable insights for power quality improvement applications and supports optimization efforts in power system design, featuring modular blocks for easy parameter adjustment and performance analysis.
