This paper presents the development of a cosimulation platform of induction motor direct torque control (DTC) drive. This paper provides advanced modeling and simulation tool for induction motor drive. The proposed simulation platform allows a coupled analysis that links finite element analysis (FEA) with the simplorer for the more realistic simulation, analysis and validation. With the help of finite...
This paper presents an improved dynamic model with incorporating the saturation effects for an induction motor (IM). The improved model is simulated with MAT-LAB/SIMULINK software for transient response in terms of electromagnetic torque, rotor speed and stator current at no-load and on-load. The obtained simulated results provide a clear evidence that the conventional unsaturated model fails to predict...
The use of multiobjective optimization technique in determining the values of the steady-state equivalent circuit parameters of a three-phase squirrel-cage induction machine is discussed. The identification procedure is based on the steady state phase current versus slip and torque versus slip characteristics. Nonlinearities in the Induction machine such as saturation effects and skin effects are...
Equivalent circuit approach is the most generally used method for the analysis of induction motor (IM). Equivalent circuit method is based on the assumption that IM operates in the linear region of magnetizing curve. However, in practice many a times motor needs to operate in the non-linear magnetic region where the magnetic saturation of the core cannot be avoided. This causes deviation in the results...
