Models of quasistationary DC machines

Information

This package contains quasistationary models of DC machines; these models are fully compatible with the transient machine models of DC machines; the only difference is that electrical transients are neglected.

Please note:

Quasistationary DC machine models are basically different from quasistationary induction machine models: Quasistationary DC machine models neglect electrical transients, i.e., setting der(i) = 0, whereas quasistationary induction machine models are based on time phasor theory, see QuasiStationary Library, where e.g., L*der(i) is replaced by j*omega*L*(I_re+j*I_im).
