Space Vector Modulation based Field Oriented Control scheme for Brushless DC motors

This paper focuses on various aspects of Space Vector Modulation based Field Oriented Control of Trapezoidal Permanent Magnet Synchronous Motors. The purpose is to introduce in a concise manner the fundamental theory, main results and practical applications of Field Oriented Control (FOC) for Brushless DC motors. The primary focus is on controlling the motor in d-q axis using field oriented control technique along with the generation of space vector modulated pulses for the inverter driving the Brushless DC motor. This vector control method improves the system performance with low torque ripple, and high efficiency is also introduced thus making it suitable for immense applications employing electromechanical actuators.
