This paper presents a straightforward method for dynamic emulation of multi-mass systems. The test bench consists of a driving motor coupled rigidly to a load servo motor, and the torque reference of the servo motor is controlled based on the dynamic model to be emulated. No additional measurements are needed, but the mechanical parameters of the test bench(More)
Saturation due to main flux and rotor leakage flux interaction appears in induction machines, particularly if rotor slots are skewed or closed. Conventional saturation models used in connection with dynamic equivalent-circuit models do not take this phenomenon into account. In this paper, explicit functions for modeling this mutual saturation are proposed.(More)
