7. Comparison with Modern Approaches
While Langsdorf’s theory is rigorous, it is primarily steady-state and phasor-based. Modern control theory (field-oriented control, direct torque control) relies on time-domain state-space models and digital implementation. However, Langsdorf’s equivalent circuits remain the basis for:
