Using One FPGA to Control Two High-Switching-Frequency PMSM Drive Systems Through a Novel Time-Division Multiplexing Method

In order to reduce the resources utilization of Field Programmable Gate Array (FPGA) chip thereby using one FPGA to control multiple motors together, a novel time-division multiplexing (TDM) method is proposed in this paper. The field-oriented control (FOC) algorithm is developed using Xilinx system generator (XSG) in Matlab/Simulink environment. Due to the fast calculation speed of FPGA and the pipeline optimization technology, the execution …
