英文摘要	In this paper time-domain analysis is performed for limit cycles in control loops that are induced by control valve stiction, and an analytical relationship between the proportional-integral controller parameters and the oscillation amplitude and period of process output is established. Based on this relationship, a novel controller design approach is proposed to achieve the desired oscillation amplitude. Compared with the qualitative controller tuning methods in the literature, the proposed approach is quantitative, and it avoids tuning the controller parameters in a trial-and-error manner for compensation of control valve stiction. The validity of the limit cycle analysis and the effectiveness of the proposed compensation approach are illustrated with numerical examples.; CPCI-S(ISTP); fanglei@pku.edu.cn; jiandong@pku.edu.cn; xbtan@egr.msu.edu; qlshang@zjut.edu.cn; 1688-1693
