庆历四年太学的独立设置,标志着北宋的教育重心从品官子弟向平民子弟转移,开启了宋代教育发展的新纪元。为弥补宋初人才培养和选拔体制的缺陷,顺应教育下移的时代发展趋势,仁宗朝廷在借鉴西汉至五代各朝中央官学体制架构的基础上,结合... 详细信息

庆历四年太学的独立设置,标志着北宋的教育重心从品官子弟向平民子弟转移,开启了宋代教育发展的新纪元。为弥补宋初人才培养和选拔体制的缺陷,顺应教育下移的时代发展趋势,仁宗朝廷在借鉴西汉至五代各朝中央官学体制架构的基础上,结合历代朝廷重臣所提的兴学建议,延续了当朝初期的太学馆制度,专为八品以下及庶民子弟建立太学,以期实现为国育才的目的。庆历四年独立设置太学受当时教育改革环境影响,是仁宗朝廷改革不合时宜的人才培养和选拔体制所取得的代表性成就,对当时及以后教育的发展产生了重要影响。

This article proposes a linear parameter varying （LPV） switching tracking control scheme for a flexible air-breathing hypersonic vehicle （FAHV）. First, a polytopic LPV model is constructed to represent the complex nonlinear longitudinal model of the FAHV by using Jacobian linearization and tensor-product （T-P） model transformation approach. Second, for less conservative controller design purpose, the flight envelope is divided into four sub-regions and a non-fragile LPV controller is designed for each parameter sub-region. These non-fragile LPV controllers are then switched in order to guarantee the closed-loop FAHV system to be asymptotically stable and satisfy a specified performance criterion. The desired non-fragile LPV switching controller is found by solving a convex constraint problem which can be efficiently solved using available linear matrix inequality （LMI） techniques, and robust stability analysis of the closed-loop FAHV system is verified based on multiple Lypapunov functions （MLFs）. Finally, numerical simulations have demonstrated the effectiveness of the proposed approach.

Identification of the Wiener system with the nonlinear block being a piecewiselinear function is considered in the paper, generalizing the results given by H. E. Chen to the case of noisy observation. Recursive algorithms are given for estimating all unknown parameters contained in the system, and their strong consistency is proved. The estimation method is similar to that used by H. E. Chen for Hammerstein systems with the same nonlinearity. However, the assumption imposed by H. E. Chen on the availability of an upper bound for the nonsmooth points of the piecewise-linear function has been removed in this paper with the help of designing an additional algorithm for estimating the upper bound.

A novel gain-scheduled switching control method for the longitudinal motion of a flexible air-breathing hypersonic vehicle （FAHV） is proposed. Firstly, velocity and altitude are selected as scheduling variables, a polytopic linear parameter varying （LPV） model is developed to represent the complex nonlinear longitudinal dynamics of the FAHV. Secondly, based on the obtained polytopic LPV model, the flight envelope is divided into four smaller subregions, and four gain-scheduled controllers are designed for these parameter subregions. Then, by the defined switching characteristic function, these gain-scheduled controllers are switched in order to guarantee the closed-loop FAHV system to be asymptotically stable and satisfy a given tracking error performance criterion. The condition of gain-scheduled switching controller synthesis is given in terms of linear matrix inequalities （LMIs） which can be easily solved by using standard software packages. Finally, simulation results show the effectiveness of the presented method.
