控制理论与应用（英文版） 2012年第3期10卷 309-318页

作者： ruliang wang Kunbo MEI Chaoyang CHEN Yanbo LI Hebo MEI Zhifang YU Computer and Information Engineering College Guangxi Teachers Education University Nanning Guangxi 530023 China School of Mathematical Sciences Guangxi Teachers Education University Nanning Guangxi 530023 China Department of Control Science and Engineering Huazhong University of Science and Technology Wuhan Hubei 430074 China Information Engineering College Capital Normal University Beijing 100048 China School of Education Sciences Guangxi Teachers Education University Nanning Guangxi 530023 China

In this paper, adaptive neural control is proposed for a class of multi-input multi-output （MIMO） nonlinear unknown state time-varying delay systems in block-triangular control structure. Radial basis function （RBF） neural net- works （NNs） are utilized to estimate the unknown continuous functions. The unknown time-varying delays are compensated for using integral-type Lyapunov-Krasovskii functionals in the design. The main advantage of our result not only efficiently avoids the controller singularity, but also relaxes the restriction on unknown virtual control coefficients. Boundedness of all the signals in the closed-loop of MIMO nonlinear systems is achieved, while The outputs of the systems are proven to converge to a small neighborhood of the desired trajectories. The feasibility is investigated by two simulation examples.

China Guangxi Normal College Nanning 530001 P. R. China Dept. of Automatic Control Engineering South China Univ. of Tech Guangzhou 510640 P. R. China

In this paper, a sufficient condition of robust D-stability for discrete-delay perturbed singular systems is presented, and the robust stability sufficient condition is independent of the delay. Two classes of perturbations for systems are discussed: (1) highly structured parametric perturbations; (2) unstructured parametric perturbations. An useful technique for robust pole-assignment in a specified circular region is also proposed, the criterion is tested easily, and convenient for the application in the engineering. Two examples have been given to validate the proposed method.

在中国古代典籍的记载中,印度地方博远、物类丰聚,圣贤叠轸、仁义成俗,杂技幻术神异奇妙,医术、天文历算等先进发达。同时,以佛教为主要载体的文化交流奠定了中印两国间友好交往的坚实基础,中国文人对佛国印度进行了缺席想象、在场阅读和倾情创作。以比较文学形象学视角对古代中印文化交流进行观照,既是对古代中印关系的一种印证与补充,又可从中得到启示与思考。

Infanticide,killing unweaned offspring in conspecifics,occurs widely among mammals,such as rodents,ungulates,and carnivores,especially in primates(Lukas and Huchard 2014).Such scenarios are often triggered by intruders that have replaced the former dominant males in nonhuman primates(Borries 1997).It has widely been viewed that infanticide is one of the solutions of sexually driven evolutionary selection:males kill infants to end lactational amenorrhea of the victim's mothers,forcing them to return to estrus and providing infanticidal males with the opportunities to sire their new offspring(Hrdy 1979).There is a broad spectrum regarding the patterns and mechanisms causing such events,referring to alternative breeding behaviors and mating systems-monogamy,polyandry,polygyny,and promiscuity(Qi et al.2020).
