- Abstract
Two different methods are used in dynamic model vector control applications of asynchronous machines. The first of these methods is to use the derivative information of the state variables based on the system observability principle. The second is the use of instantaneous active and reactive power measurement results as a new method. The classical equivalent circuit model is used in steady-state studies of parameter estimation methods. In dynamic systems, methods based on nonlinear minimization of the cost function, different initial values, and giving more precise estimation results are used. In this study, the dynamic system structure is set up as the square sum of the difference between parameter estimate values. Different parameter estimation methods were used for asynchronous machine models, and test results under no load and full load were examined. The impedance measurement results in parameter estimation methods were compared with the measurement results obtained from the model. It has been shown that the test results performed in real time are very close to the offline and nonlinear parameter estimation values and their accuracy has been proven.
