This study proposes a hybrid controller by combining a proportional-integral-derivative (PID) control and a model reference adaptive control (MRAC), which named as PID+MRAC controller. The convergence performances of the PID control, MRAC, and hybrid PID+MRAC are also compared. Through the simulation in Matlab, the results show that the convergence speed and performance of the MRAC and the PID+MRAC controller are better than those of the PID controller. In addition, the convergence performance of the hybrid control is better than that of the MRAC control.

网络空间技术发展迅速,新应用、新技术衍生的网络空间安全风险趋于复杂化和隐蔽化;建立特有的网络空间安全模型是国内外应对复杂安全威胁的常规做法,但现有的网络空间安全模型存在未来发展方向不明确、新技术衍生风险分析能力不足、网络空间安全防御评估所需的安全能力缺失等问题。本文从技术、学科、产业等视角入手,开展了现有的网络空间安全模型评估,梳理了网络空间安全技术体系的自身特点及其发展脉络,阐明了网络安全应用存在的迫切问题;着重从网络空间安全技术视角出发,提出了一种基于技术要素的网络空间安全模型体系框架,并利用已有安全技术和新兴技术验证了体系框架的安全分析能力。从完善网络空间安全技术体系核心框架、促进网络空间安全领域“产学研”协同、推进网络空间安全核心技术标准制定、体系化解决人工智能安全威胁等方面提出了发展建议,以期高效应对网络空间安全威胁、提升我国网络空间安全保障能力。

Nanopositioning and Nonlinearity Compensation for Step Imprint Lithography Tool

In this paper, the motion mode and nanopositioning accuracy in the step imprinting lithography process are presented, and the positioning errors different from the traditional errors, such as the gap error existing in the hinges of the stage structure and the random error produced during the process of the stage position adjustment, are analyzed. To avoid and eliminate these nonlinearity errors, radial basis function proportional integral derivative and position control algorithms are introduced into the macroand microdriving processes, respectively. The innovation of this driving method is that the motion locus is monotone, nonoscillatory, and a multistep approaching target, which eliminates the root of the random error by single direction driving mode and avoids the backlash error through preloading function. Driving experiments of different motion ranges prove that this nonlinearity compensation is very effective and the positioning accuracy during the step imprinting process can be improved up to 10 nm.
关键词: different nonoscillatory nonlinearity integral derivative positioning
