FPGA Implementation of the Reconfigurable Control System for AC Drives

The paper focuses on the implementation in Field Programmable Gate Arrays (FPGA) of vector control systems of the induction motor supplied from the tandem (hybrid) static-frequency converter. Reconfigurable cont rol structure ensures different strategies for operating modes with non-failed and partial-fa iled converter. The reconfiguration process introduces perturbations in the vector controlled AC drives. The paper tries to give a synthesis of the tandem vector control structure implementation. Problems related to hardware implementation of the transition from a control structure to another are discussed.
