摘　　要：闭环控制设计是核磁共振陀螺仪系统设计的关键环节之一。基于锁相环实现对核磁共振陀螺仪系统的闭环控制,并分别采用基于PI控制的环路滤波器与基于自抗扰控制的环路滤波器,设计了两种不同结构的锁相环。经过仿真验证,两种锁相环均能跟踪陀螺仪跟随载体的转动角速度,其中基于自抗扰控制技术的锁相环具有更好的动态性能与准确性。Closed-loop control design is one of the key aspects of nuclear magnetic resonance gyroscope system design.This paper implements closed-loop control of the nuclear magnetic resonance gyroscope system based on phaselocked loops,and designs two different structures of phase-locked loops using a loop filter based on PI control and a loop filter based on active disturbance rejection control.After simulation verification,both phase-locked loops can track the rotation angular velocity of the gyroscope following the carrier.Between them,the phase-locked loop based on active disturbance rejection control technology has better dynamic performance and accuracy.
