Abstract

Procedures for on-line adaptation of rotor time constant are allways based on error models considering two or more machine parameters. A mismatch betwen the parameters in the models and in the machine has strong influence on the adaptation quality and therefore on the result of field oriented control method . The parameter sensitivity of the adaptation method is analysed theoretically and investigated by means of simulation studies. A new approche to improve the parameter robustness by using a reactive power method. is shown.
