SVPWM Slip Frequency Closed-Loop Speed Control System for Three-Phase Induction Motor

This project presents a MATLAB implementation of a three-phase induction motor speed control system utilizing SVPWM (Space Vector Pulse Width Modulation) with slip frequency closed-loop control, developed for MATLAB 7.4. The system enables precise speed regulation and control of three-phase induction motors by employing SVPWM technology combined with slip frequency closed-loop control algorithms, which significantly enhances system efficiency and dynamic performance. MATLAB 7.4 provides comprehensive toolboxes and functions that facilitate convenient and flexible implementation of this control system. The implementation involves coding motor control algorithms using MATLAB's Simulink and Power System Blockset, where key components include slip frequency calculation blocks, SVPWM signal generation modules, and PID controllers for closed-loop regulation. Engineers can adapt the system to different motor specifications and control requirements by modifying parameters such as motor inductance values, slip gain coefficients, and PWM carrier frequencies through configurable script files. This implementation serves as a valuable resource for engineers and researchers to deepen their understanding and practical application of advanced control techniques for three-phase induction motors, with particular focus on real-time implementation aspects and algorithm optimization strategies.
