PMSM 的 MTPA 控制，从控制原理上详细分析了公式法 MTPA 控制无法推出解析解的问题和曲线拟合法 MTPA 控制函数高阶运算复杂、占用硬件资源大的问题。为了得到一种可工程实现、计算简单的 MTPA 控制，本文以线性插值查表法为基础设计了 MTPA 控制算法。
English Description：
MTPA of all-digital fuzzy control, are analyzed in detail from the control principle of formula MTPA control cannot launch analytical solution of the problem and curve fitting MTPA control function high order complex operation, take up the problem of hardware resources.In order to get an engineering control the MTPA, simple calculation, this paper on the basis of the linear interpolation method of look-up table MTPA control algorithm is designed.
