Optymalizacja własności dynamicznych zamkniętego obwodu regulacji prędkości kątowej silnika indukcyjnego w napędzie reaktora polimeryzacji

Dynamic properties of control system with induction motor driving the mixer of polymerizer are studied in the paper. The parameters of angular velocity controller are calculated as a result of these studies. The field oriented control system applying phase current hysteresis controllers was chosen for analysis as a typical example. Taking into consideration both equations and block diagram the logarithmic frequency responses corresponding to transfer of both set and upset signals were made. The frequency response corresponding to transfer of set signal allows adjusting the angular velocity controller. The frequency response corresponding to transfer of upset signal gives some information about the way to reduce the impact of upset signal. Basing on obtained operational relationships the presence of free vibration in mechanical subsystem is shown. The consequences of this vibration are also described.
