The speed loop dynamic response
characteristics of vector control can be
adjusted by setting the proportional coefficient
and integral time of speed regulator.
Increasing proportional gain or reducing
integral time can accelerate dynamic
response of speed loop; however, if the
proportional gain is too large or integral time
is too small, system oscillation and overshoot
may occur; if proportional gain is too small,
stable oscillation or speed offset may occur.
PI parameters have a close relationship with
the inertia of the system. Adjust PI
parameters depending on different loads to
meet various demands.

Electromotive slip
compensation
coefficient of vector
control
Slip compensation coefficient is used to
adjust the slip frequency of the vector control
and improve the speed control accuracy of
the system. Adjusting the parameter properly
can control the speed steady-state error.
