Abstract


With the permanent magnet synchronous motor (PMSM) is widely used in high-precision servo control system , the control of PMSM study has great practical significance and scientific value . In this paper, the three-phase sine wave drive permanent magnet synchronous motor in different coordinate systems , the corresponding mathematical model , based on analysis of the structure and characteristics of the permanent magnet synchronous motor . Motor mathematical model dependence shortcomings PMSM inherent strong coupling , nonlinear characteristics of time-varying parameters as well as traditional control method , based on research and analysis of predictive functional control algorithm as well as vector control algorithm , designed to predict function and Vector Control of AC servo system of permanent magnet synchronous motor combination . Predictive function control algorithm in MATLAB / SIMULINK simulation environment simulation controller design method is given , and the design of permanent magnet synchronous motor AC servo system modeling and simulation . Simulation results show that : compared with the traditional PI control system using the combination of predictive functional control with vector control of permanent magnet synchronous motor AC servo system has good dynamic and static performance to meet the system to overcome the parameters change , anti-jamming , tracking quickly and the control of high precision requirements , improve the performance of the overall control of permanent magnet synchronous motor AC servo system . Finally, the digital signal processor (TMS320F2812 DSP) hardware and software design for AC servo system of permanent magnet synchronous motor control core . CCS environment , the completion of the space vector pulse width modulation algorithm program verification , IR2130 driver circuit design , hardware and software debugging and experimental studies , the experimental results verify the correctness of the design .
