In order to reduce the periodic current tracking error of the deadbeat control when compensating abruptly changing nonlinear load current, a repetitive controller is plugged into the deadbeat controller. Also, the repetitive controller can alleviate the parametric dependency of the deadbeat control and eliminate the effects on compensation performance caused by the uncertainties in the system.
另外,为了降低无差拍控制对系统参数的依赖型和系统中存在的不确定性对补偿性能的影响以及减小在补偿电流变化剧烈的非线性负载电流过程中存在的周期性的局部跟踪误差,本文在无差拍控制器的基础上,又提出了基于无差拍和重复控制的复合电流控制器。

In this dissertation, many works have been done on the basis of the summarization of the merits of all kinds of meshless methods after a large number of relevant references are read and studied. The basic ideas, principles of meshless methods and their development in the recent years are introduced synoptically. Applications of Element-free Galerkin method in elastic foundation plate are studied deeply and some useful conclusions are obtained as follows:(1) Comparisons between numerical solutions and analytical solutions for several different styles of weight functions, including Gaussian weight function, spline weight function and singular weight function etc, are performed. The results show that Gaussian weight function is the best one.(2) Ranges of relevant parameters for Gaussian weight function are given.(3) Influences of nodal distribution schemes and the number of Gaussian integrated dots on computational results are discussed.

It is shown that polystyrene has been grafted on the surface of nmSiO2 particles and the grafting ratio is about 40%. The surface of nmSiO2 could be treated effectively by KH570in absolute ethanol at 25℃, 48h. The nmSiO2-g-PSt unpurified by toluene appear microsphere in which nmSiO2 particles are contained, whereas the purified one appear internet formed by many pieces. The grafting ratio of PSt on nmSiO2 surface could be influenced obviously by dispersion agents content and agitation speed, whereas the morphology of nmSiO2-g-PSt purified is rarely changed.
结果表明:常温下在无水乙醇介质中处理48h以上可获得良好的硅烷处理效果;PSt已接枝包覆于nmSiO2表面,接枝率约40%;经甲苯洗涤前nmSiO2-g-PSt呈多粒子包覆微球状,洗涤后呈单粒子包覆网状结构;分散剂用量、搅拌速度改变对接枝率有影响,但对包覆形态影响不大。

The pigment of Berberis heteropoda Schrenk is a type of anchocyanin and it is strong in resistance against light and to some extent, good in enduring heat and low consistence oxide. But it is poor in resistance against reductant and preservative. It can be applied to the condition of PH. It is also found that sucrose and most of metal ions do not exert negative effects on the stability of the pigment, except Fe3+, Fe2+and low consistence Pb2+, which have some extent effects. Adding stability matter can improve its stability. The harm trace elements contains are within requirement of the National Standard on food safety, As the lexicological study indicates that the pigment does not have any toxicity and mutagenesis, it can be used as edible pigment.
结果表明:大孔树脂吸附-解吸附法纯化黑果小檗色素实验室工艺简单易行,色素回收率高;黑果小檗色素属于花色苷类色素;耐光性好;对热有一定耐受性;对低浓度氧化剂有一定耐受性;耐还原性差;对防腐剂耐性差;适用PH<6条件下使用;蔗糖和大多数金属离子对色素无不良影响,但Fe~(3+)、Fe~(2+)、Sn~(2+)和低浓度pb~(2+)对色素有影响,加入稳定剂后,可提高色素的耐热性、耐氧化性、耐防腐剂能力;经对有害微量元素进行检测和毒理试验表明,该色素安全无毒,可以作为天然食用色素使用。
