Abstract :
This paper proposes a new control method for deep field-weakening operation of permanent magnet synchronous machines (PMSMs). With single current regulator (SCR) and voltage angle control (VAC), the new method can achieve much higher field-weakening speed rate than conventional methods. The SCR-VAC method makes full usage of the DC bus voltage so that maximum torque output can be obtained. It is shown by stability analysis that, d-axis current control should be used for motion and q-axis current control for generation. Conclusions are verified by experimental results.
