旋转机械中普遍存在着与位置有关而不是与时间相关的空间扰动。本文提出了一种改进的控制方法--精确周期对准重复控制(ACARC)来解决这一问题。在ACARC中，利用数据存储技术实现了空间内模型，并提出了抑制空间扰动和更好响应的设计要求。此外，通过空间低通补偿器和时间推进元件的组合，显著减小了由辅助稳定补偿器引起的周期偏差。在此基础上，提出了ACARC的级联结构，并针对实际旋转系统中存在的多分量扰动给出了详细的设计方法。通过仿真和实验验证了该控制方法的有效性和优越性，并与其他方法进行了比较。
The spatial disturbance, which depends on position rather than time, is widespread in rotary machines. In this article, an improved control method named accurate cycle aligned repetitive control (ACARC) is proposed to deal with its suppression. In the ACARC, the data-storage technique is used to realize the spatial internal model and a design requirement is presented for the rejection of spatial disturbance with a better response. Further, the cycle offset, caused by the auxiliary stabilizing compensator, is significantly reduced by the combination of a spatial low-pass compensator and a time-advance element. Moreover, a cascaded structure of ACARCs is presented together with a detailed design procedure for disturbance with multiple components occurring in actual rotary systems. The effectiveness and superiority of the proposed control method are verified and compared with other methods by the simulations and experiments.
