Asynchronous Motor Vector Control Simulation Model with Custom Implementation

This simulation model for asynchronous motor vector control employs an indirect field orientation control (IFOC) strategy, which decouples the motor's flux and torque components using coordinate transformation algorithms. The motor model is custom-developed based on the mathematical equations governing motor behavior in the two-phase rotating coordinate system (dq-frame), implemented through differential equations representing voltage, current, and flux relationships. This approach provides greater flexibility and accuracy in simulating motor dynamics under various operating conditions compared to using MATLAB's built-in motor blocks. The implementation includes Clarke and Park transformations to convert three-phase quantities to the dq-reference frame, with PI controllers regulating the torque and flux components. The simulation incorporates real-world factors such as temperature effects on resistance, voltage saturation limits, and current constraints through parameterized scripts and lookup tables. By integrating these physical considerations, the model enables comprehensive analysis of motor performance across different load conditions and operating points. Key functions include: - Rotor flux estimator using slip frequency calculation - Space Vector Pulse Width Modulation (SVPWM) for inverter control - Real-time monitoring of torque ripple and flux linkage This customizable simulation framework serves as an effective platform for developing and optimizing vector control strategies, with modular code structure allowing for easy modification of control parameters and motor characteristics.
