vektorstyrning
Vektorstyrning, also known as vector control or field-oriented control (FOC), is an advanced control method used for AC electric motors. It allows for precise control of both the motor's torque and speed independently, mimicking the behavior of a DC motor. This is achieved by mathematically transforming the stator currents of the AC motor into a rotating reference frame aligned with the rotor's magnetic flux.
The core principle of vektorstyrning is to decompose the stator current into two components: one that generates
The implementation of vektorstyrning typically requires a motor model, a speed sensor (though sensorless versions exist),
