摘要
Abstract
In allusion to the issues of slow response and high cost of software field-oriented control(FOC)strategies that cannot meet the new control requirements in the field of permanent magnet synchronous motors(PMSM),an FOC application-specific integrated circuit(ASIC)is designed.The chip architecture is designed based on a dual closed-loop control structure,and VerilogHDL(hardware description language)is used to design modules such as FOC,coordinate rotation digital calculation(CORDIC),current sampling interface,encoder interface,and serial communication.The parallel acceleration is implemented by means of the hardware architecture.The ModelSim platform is used to simulate and verify the functionality of the designed circuit,and a chip physical verification platform is built with FPGA as the core,so as to control the current and speed of PMSM.The results show that the designed ASIC output PWM signal can reach 12.2 kHz,and the double loop frequency can reach 12 kHz and 8 kHz,respectively,which has fast dynamic response and good steady-state characteristics.It can realize high performance,low cost and portable motor control,and has a certain application value in the field of motor control.关键词
