Transient Response Characteristics of an A-C Servomotor Excited Nonsinusoidally and Through Nonlinear Source Impedances

This paper demonstrates that it is now possible to get good correlation between predicted and measured performance of a-c servomotors during transients in nonlinear systems. The use of a large-scale digital computer as an analog device eliminates difficulties previously associated with analog computer inaccuracies. Calculated and measured curves are presented to show the behavior of the servomotor under a variety of operating conditions involving nonsinusoidal excitation through nonlinear discontinuous source impedances.
