Therefore, a design scheme via LMI approach is presented in order to improve the system robustness. By using the LMI approach, the attitude controller design is reduced to a convex optimization problem based on the polytopic system. Since there are some degrees of freedom when solving the LMI, it is available to use this kind of freedom to achieve multi-objective control within this framework.

Evidently,Huang has ahigh regard for micro social study including the study of local history;he attaches importance to first-hand data and perceptualknowledge obtaining from the study of anthropological method;he attaches importance to the ponderation and discrimination of ex-isting theories from historical facts;he insists on the sequence of recognition going from historical facts to theory,and back to his-torical facts again and so on.

认为黄宗智教授尖锐而深刻地指出了目前中国社会经济史研究中存在着&规范认识危机&，他的两部专著的基本研究方法和思路——推重微观的社会研究，包括地方史研究，重视从人类学方法研究得来的第一手资料和感性认识，重视从史实出发对既有理论的思考和辨析，执着从史实到理论、再回到史实的认识程序，等等。

Through theoretical, comparative, demonstration study and so on and the analysis of the nature and characteristics of the credit system, The thesis has put forward the conception of the Three-credit system for vocational schools: On the basis of the credit system and according to its general principle the teaching management in vocational schools divides the original credit system into three types of credits: creditof theoretical knowledge, special techniques and integrated quality with each covering a certain proportion. Each type has its own corresponding time request and evaluation forms. In each type students are, to seme extent, allowed to do some choices on their own.

本论文运用了理论研究法、比较研究法和实证研究法等研究方法，从分析学分制的本质及特点入手，提出了三元学分制的概念：中等职业学校三元学分制是中等职业学校教学管理以学分制为基础，遵循学分制的一般原则，将原来单一的学分形式分解为理论知识学分、专业技能学分、综合素质学分三类学分，三类学分之间有一定比例，每类学分有一定的课时要求和相应的评价考核办式，学生在每类学分选修中有一定的自主权，在达到规定的学分总数后即可毕业。
