Device and method for generating an initial controller lookup table for an IPM machine |
摘要 |
Embodiments of the present invention provide a device and method for generating initial operating points for controlling an interior permanent magnet (IPM) machine. The method includes loading an inductance lookup- table (S110), first calculating a maximum torque per Ampere (MTPA) trajectory for a first threshold speed based on machine parameters of the IPM machine (S120), second calculating a truncated voltage limit ellipse with monotonicaliy increasing torque for a first speed based on the machine parameters (S130), if the first speed is higher than the first threshold speed, determining an operating trajectory at the first speed (S140) based on at least one of the calculated MTPA trajectory and the calculated truncated voltage limit ellipse, and generating an I |
