【Abstract】 System Generator (SG) is efficient high level design tool based on FPGA. MATLAB/Simulink is one of the most popular simulation tools to build offline model. Combined with the advantages of the two software, a novel approach for SG/Simulink hybrid modeling and simulation of Brushless DC motor (BLDCM) control system is presented. Using the professional SG tools, the design procedure of the model of BLDCM control system is illuminated. When the control algorithm is implemented in an FPGA, SG tools can be used to not only exactly simulate the hardware but also automatically generate the necessary VHDL codes of the control model. The reasonability and validity of the hybrid modeling and simulation method have been testified by the simulation results.更多还原
