The control of a synchronous permanent magnet machine by means of direct control of stator flux using a novel Anti-Windup scheme is presented. The proposed strategy achieves torque control through load angle imposition and ensures maximum torque per ampere operation through the careful adjustment of the stator flux vector magnitude. The flux controller is implemented using a novel anti-windup scheme that allows the correct relation between d and q voltage components. The stator voltage is generated using space vector modulation (SVM) in a standard voltage source inverter.
