    • A control system and method for an electric machine includes a first calculation module that receives a modified torque command and a calculated stator flux command and that generates first and second current commands and first and second voltage commands. A voltage magnitude calculation module generates a voltage magnitude based the first and second voltage commands. A reference voltage calculator module generates a reference voltage based on a DC link voltage, an angular stator velocity and the first and second current commands. A flux weakening module generates the calculated flux command based on the angular stator velocity, the reference voltage and the voltage magnitude.
    • 一种用于电机的控制系统和方法包括:第一计算模块,其接收修改的转矩指令和计算的定子磁通指令,并产生第一和第二电流指令以及第一和第二电压指令。 电压幅度计算模块基于第一和第二电压命令产生电压幅度。 参考电压计算器模块基于DC链路电压,角定子速度和第一和第二电流命令产生参考电压。 磁通弱化模块基于角定子速度,参考电压和电压幅度产生计算的磁通指令。
