Abstract :
This paper presents a method of estimating the initial rotor position of a cylindrical permanent magnet synchronous machine without a position sensor. The closed-loop controlled torque start-up is proposed using a structured adaptive flux observer, which allows the start-up with the optimal high torque in severe starting conditions with the least possible motor current. The method is proved to be valid based on simulation and experimentation.
