Abstract：In this paper, the design of a maximum torque current ratio control FPGA for PMSM is proposed to improve the response speed and steady-state characteristics of electromagnetic torque as well as to reduce the ripple of the flux linkage, which has good dynamic characteristics. In the data processing aspects of a custom way to deal with fractional computing, which greatly improves the system accuracy, but also take into account the optimization of system performance and resource allocation. It is verified that the control strategy has a good dynamic response, steady-state characteristics, small torque ripple and strong robustness to the change of parameters of PMSM at full speed. It is a high-performance AC speed regulation method.
