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 accurate
motor parameter models, the accuracy of motor parameters affects vector control performance. It is
recommended to enter accurate motor parameters and autotune motor parameters before executing
vector control.
