高频时变负载下大规模离散系统的双层滑模控制研究
Research on Double Layer Sliding Mode Control of Large Scale Discrete Systems under High Frequency Time Varying Loads
摘要
Abstract
To address the insufficient robustness in controlling large-scale discrete high-order sys-tems during the drilling processes of rotary drilling machine under high-frequency load mutations,a double-layer sliding mode control(DLSMC)strategy was proposed based on distributed control princi-ples.For pressure control applications,the proposed sliding mode control scheme demonstrated faster response speed and smaller errors compared to traditional PID and adaptive control methods.A con-trolled comparative analysis was implemented through paired borehole testing in geologically homoge-neous formations,systematically evaluating drilling dynamics under controller-active and controller-absent configurations.The results show that the uncontrolled system experiences approximately 15 in-stances of power head rotational speed dropping to 0,10 torque fluctuations with amplitudes around 100 kN·m,and 3 jamming incidents during drilling.In contrast,the controlled system maintains stable power head rotational speed and torque without any jamming occurrences.These findings vali-date the effectivenesses of the anti-jamming control strategy and provide a foundation for intelligenti-zation of complete drilling systems.关键词
