Abstract

The torque feedback control method has been proposed as a control method in the weakening flux region for interior permanent magnet synchronous motors (IPMSM).When applying this control method to the two-level inverter system, a method for determining the voltage margin method has not been studied. In addition, an analytical design method has not been studied. In this paper, a method to design control gains is proposed for the already proposed control feedback method by means of the linearized method. Furthermore a method to determine the voltage margin to secure the torque control performance is proposed. This method is verified by experimental tests with a 1-kW motor system.
