Modeling and cosimulation of FPGA-based SVPWM control for PMSM

Abstract

This paper presents the modeling and cosimulation method of a FPGA based permanent magnet synchronous machine (PMSM) control system; the current control loop of PMSM control system is space vector pulse width modulation (SVPWM); a new FPGA based top-down design method is proposed. According to the design method, the function model is built in Matlab environment, and the behavioral model (VHDL model) is programmed in the synthesis software platform. In order to realize the hardware/software codesign, the cosimulation between function model and VHDL model is implemented by integrating two models into one cosimulation model. By the cosimulation, the hardware timing and the function simulation can be tested and verified at the same time. In this paper, the case study shows that the design efficiency can be improved greatly by using this cosimulation method.
