Comparative Evaluation of Simplified and Complex IPM Machine Models on Control Development for Traction Applications

The paper presents a comparative evaluation of simplified and complex interior permanent magnet (IPM) machine models for control development in traction applications. It is shown that although control implementation using the complex model could result in better IPM machine performances, in practice, validation of complex model is significantly complicated and deviations from assumed parameters may compromise the performance of the control scheme. It is demonstrated that the simplified model of which validation is simpler may provide similar performance compared with the complex model. Thus, the simplified model-based control method can be considered for traction applications at the earlier stage of control development or when validation of the complex machine model is difficult.
