Abstract
Improvement of the dynamic properties of DC drive in the field weakening range was the aim of investigation. The non‐linear model of the drive system was applied. In the paper results of the comparative analysis of two emf control structures are presented. The classic emf control structure with subordinated excitation current control loop was compared with this one consisting of a non‐linear compensation block. For both control structures different kinds of the parameter designing for the emf and excitation controllers are considered. Verification of the theoretical assumptions and synthesis methods of the investigated control structures are made by simulation tests using the PSpice language.
