Sažetak
A mathematical model of permanent magnet
synchronous motor is described in this thesis. The
described model is equivalent to a model of classical
separately excited DC motor with constant exication.
An electric drive is described. Software package
suitable for Sinamics electric motor is Starter
V4.3. Regarding optimization PT2 setpoint filter
is disabled, which appears in starting model, and
according to that new parameters were calculated
for current (torque) and rotational speed controllers.
A setpoint filter of rotational speed was set and time
constant of rotational speed feedback was adjusted.
With usage of optimized parameters a quicker
response of rotational speed with smaller overshoot
is achieved, while current is still within allowed
limits and compensation of disturbances is better.
