Hardware in loop methodologies for the control of dual-PMSM connected in parallel: FPGA implementation and experimentation

The focus of this article is to study the Hardware In the Hoop (HIL) generic methodology for the design of a universal real-time control. FPGAs (Field Programmable Gate Arrays) are used to control a DPMSM (Dual Permanent Magnet Synchronous Machine) variable speed drive supplied by a Dual-PWM Voltage Source Inverters (VSIs). The load of the two PMSMs can be either separated or in common and are controlled by individual vector controls associated with a PWM modulator in a first step. In a second step we will realize a comparative study between the responses of the mathematical model and the real system. The implementation of the different control configurations is done using the dSPACE DS52030D digital platform containing DSP and Xilinx FPGA. An efficient solution is proposed in which the software part is managed by a Matlab-Simulink layer. This method allows a material library to be built which can be used for other control systems based on a PMSM.
