摘　　要：针对采用模拟电路、MCU等技术实现的有限转角电机控制器在控制精度、响应速度上存在的不足,引入FPGA硬件平台,设计一种基于FPGA的有限转角电机控制器。设计采用RDC19222旋转变压器、AD7091R传感器来解析上级系统指令信号和电机转子实时位置、实时角速度、实时母线电流信号等,完成对有限转角电机转子位置的三闭环控制。实验结果表明,基于FPGA的有限转角电机控制器能够有效提高PID控制精度与控制器响应速度,有助于进一步推进有限转角电机操动技术的发展。In view of the shortcomings in control accuracy and response speed of the finite rotation motor controller realized by analog circuit and MCU technology,an FPGA-based finite rotation motor controller is designed by introducing FPGA hardware platform.The RDC19222 rotary transformer and AD7091R sensor are used to analyze the command signal of the superior system,the real-time position of the motor rotor,the real-time angular velocity and the real-time bus current signal,etc.,so as to complete the three closed-loop control of the rotor position of the motor with finite rotation angle.The experimental results show that the controller based on FPGA can effectively improve the PID control accuracy and the response speed of the controller,which is helpful to further promote the development of the operation technology of the motor with finite rotation.
