同步磁阻电机dq轴交叉耦合饱和电感模型参数寻优方法
A Parameter Optimization Method for dq Axis Inductance Model of Synchronous Reluctance Motors Considering Cross-Coupling Magnetic Saturation
摘要
Abstract
The performance of vector controlled system is greatly influenced by the non-linear changes of d axis inductanceLd and q axis inductanceLq of a synchronous reluctance motor according to different d axis and q axis current. The dq axis cross-coupling saturation inductor model was constructed with 8 constants in a synchronous reluctance motor driver. In order to find the optimal parameters, based on the design parameters of a transversally laminated anisotropic rotor synchronous reluctance motor, the measurement results ofLd &Lq were measured by general small current method, and a minimum average variance model was established. In addition, the weights were set up for different objective functions. An improved harmony search optimization algorithm was used, and thus the optimal solution was obtained, which was close to the real information of the motor. The method was proved in a load test.关键词
