摘要
The paper presents a mathematical model for a current-controlled inverter-fed induction motor drive. The model takes into consideration dynamics of an induction motor and dynamics of a DVC power supply with current feedback. A singular perturbation method is presented to decompose this nonlinear full order system into two separate lower order subsystems: the linear fast subsystem and the bilinear slow subsystem. The separation of time scales greatly simplifies the analysis of dynamics and of the controller design.
