摘要：

The magnetic flux of induction motors fed by current-source or current-controlled voltage-source inverters is normally controlled indirectly and considerably influenced by rotor temperature. Since the installation of temperature sensors conflicts with achieving a sturdy drive, indirect detection using only easily measurable quantities is desired. Online observation of the machine by a model implemented in a microcomputer allows closed-loop estimation of the disturbing temperature. Requirements on the accuracy of the model and the measured data are discussed. The feedback from the estimation program to the analog inverter control is demonstrated. Experimental results are included.
