Driver System Design and Control of a Certain Type of High Speed Motor
The basic principle and control strategy of AC motor vector control are studied.The MOSFET power transistor made of SiC material forms the current conversion link,which has the advantages of high switching speed and low switching loss.The structure of ARM+DSP+FPGA is selected in the control part,and the control reliability and precision are improved.Finally,the simulation experiment is carried out on the simulation software PLECS,and the experimental parameters are adjusted.The final simulation re-sults show that the system with vector control has good performance and can meet the requirements of high-speed motor drive for 65 kW and 36 000 r/min.
