Three-Level SVPWM Vector Control Simulation Model

This paper presents a three-level Space Vector Pulse Width Modulation (SVPWM) vector control simulation model that incorporates sensorless vector control using the Model Reference Adaptive System (MRAS) algorithm. The primary objective of this model is to achieve high-efficiency motor control with precise positioning capabilities. The implementation utilizes MRAS-based speed estimation technology to accurately obtain motor speed information without requiring physical speed sensors, enabling sophisticated vector control operations. This control methodology enhances motor efficiency and performance characteristics through algorithmic compensation of speed estimation errors and adaptive parameter tuning. The simulation model demonstrates practical implementation of voltage vector sector identification, duty cycle calculation for three-level inverters, and real-time adaptation mechanisms for robust motor control. This advanced control approach offers significant performance improvements and shows promising application potential in various industrial drive systems.
