摘要
针对音圈电机位置控制系统内外扰动对系统控制精度及鲁棒性的影响,提出一种基于自抗扰算法的音圈电机位置控制策略.在建立音圈电机数学模型的基础上,利用线性扩张状态观测器估计系统的内外扰动,在线进行动态扰动补偿.仿真结果表明,与经典PID控制相比,基于自抗扰的音圈电机位置控制策略能够有效克服内外扰动对系统性能的影响,具有响应快、无超调、抗干扰能力强等优点,有较好的工程应用前景.
Internal and external disturbances of position control of voice coil motors have impacts on accuracy and robustness of system control.To address such impacts,a position control strategy of voice coil motor based on ADRC algorithm is proposed.On the basis of establishing the mathematical model of voice coil motor,linear extended state observer is used to estimate the internal and external disturbances of the system and compensate for the dynamic disturbances online.The simulation results show that,compared with classical PID control,the position control strategy of voice coil motor based on ADRC can overcome the impacts of internal and external disturbances on the system performance.This strategy has advantages of fast response and strong anti-interference ability without overshoot,and thus has a bright future for engineering applications.
