| Abstract |
In induction machines with field-oriented control the knowledge of the rotor time constant is of great importance. Because it is not constant, the continuous identification of the rotor time constant is necessary. In this paper a method is presented that provides the possibility to estimate the stator resistance besides the identification of the rotor time constant. The stator voltage, the stator current and the speed are assumed to be known. The identification of the rotor time constant and the stator resistance is realized using parameter estimation techniques and an additional model. Because test signals are not applied the identification does not cause a deterioration of the behavior of the speed controlling system. The identlfication can be done under steady-state or transient load conditions. |
