摘　　要：针对软件矢量控制策略因响应慢、成本高而无法满足永磁同步电机(PMSM)领域控制新需求的问题,设计一种矢量控制专用集成电路(ASIC)。采用双闭环控制结构为基础设计芯片架构,使用VerilogHDL硬件描述语言设计矢量控制、坐标旋转数字计算(CORDIC)、电流采样接口、编码器接口和串口通信等模块,通过硬件架构实现并行加速。利用ModelSim平台仿真验证所设计电路的功能,以FPGA为核心搭建芯片物理验证平台,控制PMSM的电流与速度。结果表明:所设计的ASIC输出PWM信号达到12.2 kHz,双环频率分别达到12 kHz和8 kHz,具有快速动态响应与良好的稳态特性;且能够实现高性能、低成本、可移植的电机控制,在电机控制领域具有一定的应用价值。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.
