克里考特是大地伦理学的重要继承者与阐释者,并为大地伦理学的哲学理论提供了思想基础。尽管国内外学者已经从多种角度对克里考特的环境伦理思想进行了深入研究,但是并没有对克里考特的根本性理论前提,即世界观与价值观的统一性进行探究。而克里考特就是基于世界观与价值观的统一性这一根本性理论前提来对大地伦理进行阐释与辩护的。为了弥补学界的研究空白,分析了克里考特环境伦理思想中的世界观与价值观统一性观点,并且探究了它如何作为克里考特的理论前提来为大地伦理进行阐释与辩护。

作者： yu-long Fan Chuan-Ke Zhang Yong He the School of Automation China University of Geosciences the Hubei Key Laboratory of Advanced Control and Intelligent Automation for Complex Systems the Engineering Research Center of Intelligent Technology for Geo-Exploration Ministry of Education IEEE

Dear Editor,This letter is concerned with stability analysis and stabilization design for sampled-data based load frequency control(LFC) systems via a data-driven method. By describing the dynamic behavior of LFC systems based on a data-based representation, a stability criterion is derived to obtain the admissible maximum sampling interval(MSI) for a given controller and a design condition of the PI-type controller is further developed to meet the required MSI. Finally, the effectiveness of the proposed methods is verified by a case study.
