摘要

磁通水平的最佳选择对磁场定向控制异步电动机的运行至关重要。本文推导了非线性电机模型下定子和转子磁链FOC的最大转矩表达式。一方面，非线性转子磁链FOC的表达式仅比线性情况稍微复杂，而非线性定子磁链FOC的表达式则明显复杂得多。另一方面，磁场减弱区转子磁链FOC的方程仅比定子磁链系统的方程略复杂。然而，对于转子磁链FOC，可以推导出一个合理的近似，该近似易于使用。

Magnetizing current control strategies for nonlinear indirect field oriented control

The optimal choice of the flux level is of uttermost importance for operating an induction motor with field oriented control (FOC). In this paper expressions are derived to obtain maximum torque for both stator and rotor flux FOC with a nonlinear motor model. On the one hand it is shown that the expressions for nonlinear rotor flux FOC are only slightly more complex than for the linear case, while nonlinear stator flux FOC yields significantly more complex equations. On the other hand the equations for rotor flux FOC in the field weakening region are only slightly more complicated than those for the stator flux system. However, for rotor flux FOC, a fair approximation can be derived, which is easy to use.
