Method for diagnosing load angle in field-oriented control of induction machine, involves comparing target load angle value with secondary load angle value, and performing error detection based on evaluation of comparison result
The method involves determining the desired load angle value for a sampling period based on the phase current command values. The secondary load angle value for the sampling period is determined based on the measured phase current values. The single phase (U,V,W) is determined, and the determined target load angle value is compared with the determined secondary load angle value. The error detection is performed based on the evaluation of the comparison result. An independent claim is included for device for operating induction machine.
