5.5.3 Vector control
AMs feature high order, nonlinearity, strong coupling and multi-variables, which increase
difficulty to control AMs during actual application. The vector control technology solves this
situation as follows: measures and controls the stator current vector of the AM, and then
decomposes the stator current vector into exciting current (current component that generates
internal magnet field) and torque current (current component that generates torque) based on
field orientation principle, and therefore controls the amplitude values and phase positions of
the two components (namely, controls the stator current vector of the AM) to realize decoupled
control on exciting current and torque current, thus achieving high-performance speed
regulation of the AM.
The VFD uses the sensor-less vector control algorithm, which can be used to drive AMs and
permanent-magnet SMs simultaneously. As the core algorithm of vector control is based on
