Speed Control of PMSM Motor by FOC Method Using MATLAB & Simulink

Field-oriented control is a vector control method that allows for accurate and independent control of flux and torque in permanent magnet synchronous motors. By transforming stator currents into a rotating reference frame aligned with the rotor flux, FOC decouples torque and flux control, allowing for independent adjustment of both. This results in high-performance operation with a fast dynamic response, high efficiency, and a wide speed range. FOC finds widespread application in various industries, including automotive, robotics, and renewable energy systems. Field-Oriented Control (FOC) constitutes a highly effective method for controlling permanent magnet synchronous motors. It allows independent control of the motor’s torque and flux, making it highly efficient and responsive.
