Abstract

The main feature of synchronous reluctance machine (SynRM) is highly nonlinearity for flux-linkage, due to magnetic saturation and cross-saturation effect. Maximum torque per ampere (MTPA) control focuses on minimizing copper loss, which is a popular and important method for SynRM high-efficiency control. In this study, an improved golden section searching method (GSSM) is proposed for fast MTPA acquisition, taking into account nonlinear magnetic saturation and cross-saturation effect. Compared with traditional GSSM, the key feature is to use the MTPA optimal angle from the last iteration to optimize the initial search interval, thereby improving the system convergence speed and reducing computing resources. The proposed GSSM can be easily implemented with several iterations with a standard drive. The proposed algorithm has been implemented by a digital signal processor (DSP)-based 15-kW SynRM variable frequency converter.
