Transient responses of combined regenerative and rheostatic braking for DC chopper-fed motors

The possible modes of operation are explained and the dynamic equations for the combined regenerative and rheostatic braking of dc chopper controlled series motor are derived. A computer-based piecewise linear technique is used to analyze the transient responses, taking the full account of nonlinearities such as the magnetic saturation and the product of variable terms. The responses in the transient conditions, which occur in practical situations, are predicted by a computer model and are compared with the practical measurement.
