Research And Implementation Of PMSM Vector Control System Based On FPGA

PMSMs are widely used in automation,consumer electronics,medical and lab equipment,and automotive amongst others.The Electronic automation that in recent years has made a significant impact on the development of complex and compact high performance control architecture for industrial motion systems is a significant revenue contributor to the PMSM market.Specific hardware with the field programmable gate array(FPGA)technology is now considered as a promising solution in order to make use of the reliability and versatility of controllers.FPGAs have been successfully used in many control applications such as power converter control and electrical machines control.This is because such an FPGA-based implementation can offer an effective reprogrammable capability and overcome disadvantages of microprocessor-based or digital signal processor-based embedded systems.This thesis aims to provide a proof-of-concept for the control-system-on-chip and a prototype for a fully-implemented FPGA control architecture for permanent magnet synchronous motor(PMSM)drives.Firstly,a special focus is given on mathematical model of PMSM.Based on vector control principle,I stydied the Speed-current double closed-loop core algorithm of PMSM.Secondly,in order to obtain better dynamic performance,an improved particle swarm algorithm is applied to tuning of the PI parameters of the speed loop,and then the model is verified by Simulink Simulation.Thirdly,briefly introduced the APSo C hardware system architecture and set up the hardware control circuit of the control system.,and selected Zedboard as the control board,using the hardware and software collaborative control tools to complete the Speed-Current Closed Loop Control Algorithm of PMSM in the PL(Programble Logic)section of FPGA.Finally,the performance experiment of the control system is introduced and the software and hardware are fully tested.Through the Double-Closed-Loop test results of the speed and current of the PMSM vector control system,then the current-voltage waveform diagram of the PMSM was obtained,which proved the feasibility of the control system.
