Stability and Robustness Analysis of an Adaptive Algorithm for Quasi-periodic Disturbances Rejection

IntroductionThere exist several approaches to tackle periodicdisturbance rejection problems. One approach is based onrepetitive or learning control principles[1], it has gainedsome popularity in various applications where periodicdisturbances rejection or repetitive tracking is required.These applications include the control of disk drives[2],rejection of load disturbances in steel casting process[3],eccentricity compensation in rolling[4] and so on.

一种卷绕传输系统的建模、辨识与混合灵敏度H∞鲁棒控制

介绍了一个由开卷轴、拖动轴、收卷轴和两个张力感应器组成的织物卷绕传输系统的建模及模型的参数辨识，并采用混合灵敏度多变量H∞鲁棒控制来改善系统的控制性能，减少织物张力与速度之问的耦和。
