Exploration on the Integration of CAD Course and National CAD Grade Certification Training

Based on the syllabus and standard of National CAD Grade Certification issued by the Ministry of Education and China Figure Association, this paper discusses the teaching model of combining classroom teaching with skill grade certification in voca- tional college. To achieve the unity of classroom teaching and skill training can save training costs and increase the significance of classroom teaching. Implementation of integrating mechanical CAD curriculum and national CAD grade certification training is the extension of teaching reform. It can make the vocational college students obtain the professional qualification certificates besides di-plomas.

Appraising the performance of high school teachers based on fuzzy number arithmetic operations

This paper presents a new method for appraising the performance of high school teachers based on fuzzy number arithmetic operations. It uses fuzzy numbers to represent fuzzy grades. The fuzzy weights of criteria are automatically generated from the opinions of evaluators. The simplified fuzzy number arithmetic operations are used for calculating the average of fuzzy numbers. It can appraise the performance of high school teachers in a more flexible and more intelligent manner.     

C-R模糊模型在连续搅拌反应釜中的应用

针对化工生产过程中强非线性对象的动态建模问题,本文提出了具有代表性的连续搅拌反应釜的非机理模糊建模方法。从系统的输入输出数据出发,根据辨识精度将系统空间划分为个子空间,然后由隶属函数将子空间模型联接成全局模型来表征系统的整体非线性特性。仿真结果表明,该模型输出能够很好地跟踪系统的参考输出,效果明显。     

Output regulation of two-time-scale hyperbolic PDE systems

This paper addresses the output regulation of flow systems described by a class of two-time-scale nonlinear PDE systems. Within the framework of singular perturbation, the reduced-order slow model comprised of first-order PDEs coupled with ODEs is obtained. Based on the numerical approximation technique and the solvability of an inertial manifold, the finite-dimensional nonlinear model with nonlinear input is developed in this paper. Extending from the geometric control method, the non-distributed nonlinear controller can be synthesized. A combination of the state-space internal model control scheme, the reduced observer-based controller can asymptotically attenuate the effect of external disturbances. Finally, the developed methodologies are successfully applied to the development of a PFR system asscociated with the cooling coil apparatus.
