Abstract

The invention describes a control arrangement (1) of a multiple-stator machine (2), comprising a frequency converter (20_1, 20_2) for each of the plurality of stators and a controller (1_1, 1_2) for each frequency converter (20_1, 20_2), wherein a controller (1_1, 1_2) of a frequency converter (20_1, 20_2) is realized to generate control signals (120_1, 120_2) for that frequency converter (20_1, 20_2) on the basis of current values (I abc1 , I abc2 ) relating to that stator, and to generate a compensation current value (I dq_comp1 , I dq_comp2 ) for a further controller (1_1, 1_2) on the basis of the received current values (I dq1 , I* dq1 , I dq2 , I* dq2 ) in the event of an open-circuit fault in a frequency converter (20_1, 20_2); to receive appropriate input signal ( e ), a compensation current value (I dq_comp1 , I dq_comp2 ) from a further controller (1_1, 1_2); and to compute a voltage reference (V* dq1 , V* dq2 ) for a subsequent transform stage (11) and PWM stage (12) of the controller (1_1, 1_2) on the basis of the received current Values (I dq1 , I* dq1 , I dq2 , I* dq2 , I dq_comp1 , I dq_comp2 ) coming from the reference computation blocks (13, 14). The invention further describes a current control module (10) of a frequency converter controller (1_1, 1_2) of such a multi-stator machine (2); a multi-stator machine (2); and a method of performing fault-tolerant control of a multi-stator machine (2).
