Vector Control System Utilizing SVPWM Modulation Technology

The vector control system adopts Space Vector Pulse Width Modulation (SVPWM) technology and utilizes Simulink for control system simulation, achieving precise system control and analytical modeling. SVPWM represents an advanced modulation technique that delivers higher system efficiency and faster dynamic response. Implementation typically involves coordinate transformation algorithms (Clarke/Park transforms) and sector identification logic for optimal voltage vector synthesis. By integrating SVPWM technology into the control system, significant improvements in system performance and stability are achieved, while simultaneously reducing energy losses and acoustic noise. The Simulink simulation environment facilitates system design and testing through modular blocksets for PWM generation, PI controller tuning, and real-time waveform analysis. Key functions include duty cycle calculation modules and switching sequence optimizers that minimize harmonic distortion. In summary, the SVPWM-based vector control system, simulated via Simulink, not only meets precise control requirements but also enhances overall system performance and stability through optimized switching patterns and digital implementation capabilities. The simulation model typically incorporates three-phase inverter blocks, rotor flux observers, and speed regulation loops for comprehensive validation.
