On the issue of control system adjustment of a direct current drive on the modulus optimum. Part 2

Resumo

The results of simulating the most widespread variants of dc electric drives with optimum adjustments of the parameters taking into account the natural and artificial constraints of variables in MATLAB and Simulink are presented. Particular attention is given to the modes of armature current constraints, the influence of constraints on electric drive parameters, and comparative analysis of transient processes when a drive is started. It is shown that the system with a PI speed controller and a P current controller, which is adjusted to the modulus optimum has the best indices of overshooting and speed of response taking into account the artificial constraint of the armature circuit current and the natural constraint of the converter output voltage. The one-loop control system with a PI controller, also adjusted to the modulus optimum, has similar indices.
