| Abstract | ||||
| This paper presents a robust direct torque control of an interior permanent magnet synchronous motor (IPMSM) based on a sliding mode controller. The sliding mode control (SMC) law is designed in such a way that the chattering effect is reduced and the problem of reaching phase stability is eliminated. A space vector modulation is combined with the SMC to ensure minimum ripple content and high resolution voltage control. To demonstrate the validity of the proposed scheme, the calculated motor speed, estimated motor torque, stator flux and stator current in the presence of iron losses are compared with those measured in the literature. It is concluded that consideration of iron losses in the dynamic model of the machine improves the theoretical predictions and reduces the discrepancies between the calculated and measured values. | ||||
