Theory and simulation of vector control based on rotor position orientation of rare-earth permanent magnet motor

Since the rare-earth permanent materials were invented, all kinds of PM motors and their relevant control methods have been booming. Requirements on high efficiency and flexible control systems are the core of its development. Vector control method based on rotor position orientation of rare-earth PM is presented under this case, and it has so many control qualifies that general DC motor and PM motor cannot reach. This paper gives results and analysis on simulation of a real PM motor by using this control method, and gets conclusion that this control method makes PM motor has the qualifies like that of a general DC motor. A concept of state flow-chart is induced in this paper to judge the feasibility and the integrality of a control system.
