PMSM simulation model and system test based on TMS320F28035

In this paper, a model of Permanent Magnet Synchronous Motor (PMSM) using vector control algorithm is built and simulated by MATLAB/Simulink based on TMS320F28035 DSP chip. Firstly, the principle of vector control theory and the mathematical models are expounded clearly. Then, the simulation system model is established according to the method adopted by motor and the target board type, moreover, the functions and parameter settings of the peripheral modules are introduced in detail. Finally, the whole system is configured to generate the C-language project codes and downloaded to hardware circuit to debug through the automatic code generation technology. The experiment results show that the vector control algorithm has outstanding performance for PMSM and can achieve stable variable-speed functions.
