Direct Torque Control MATLAB Source Code

Implementation of traditional Direct Torque Control MATLAB simulation with modular system design, including comprehensive explanation of basic structure and principles for asynchronous motor DTC. The simulation has been successfully tested and validated with excellent performance results.

Simplified Three-Phase Phase-Locked Loop Simulation Model Implementation

Developing simplified three-phase PLL simulation models using MATLAB components by retaining only essential operations (e.g., abc-dqz transformation computing only Vq), removing frequency feedback and auto-tuning modules. Constructs single-phase PLL computational models with simplified architecture while preserving necessary PI controllers. Validates dynamic/static performance for 45-65Hz input frequency variations. Simulates and analyzes locking behavior under three-phase inputs containing harmonics, imbalances, and DC offsets.
