针对多变量、非线性、强耦舍性的倒立摆系统,采用牛顿一欧拉法建立了其动力学方程,并进行了线性化处理,得到了状态空间模型,从而设计出一种传统PID控制方案,实现了对摆杆的稳定控制。最后在MATLAB环境下进行了计算机仿真,仿真结果表明,摆杆角度控制过程具有良好的动态性能和稳态性能,验证了建模的正确性和控制方案的有效性。 相似文献

内部控制制度是指单位为了保证业务活动有序进行、确保信息质量真实可靠、保护资产安全完整、实现经营管理目标等而制定和实施的一系列控制职能的方法、措施和程序。由于电算化信息系统的建立和运行的复杂性,会计控制的范围相应地扩大了,使原有的内部会计控制制度失去作用。本文分析了会计电算化对会计内部控制的影响,尝试了一套适合电算化会计信息系统的内部控制制度,实现了电算化信息系统下的会计控制。 相似文献

Understanding learning disabilities (LDs) as constructed through multiple cultural practices including discourse, this paper focuses on a Latino middle school student with a LD named Elijah. This study documents both the discourses and practices used to position Elijah as a mathematics learner, as well as his use of similar discourses as he constructs a complex set of self-understandings as a mathematics learner. Elijah is positioned by discourses that prioritise speed as an indicator of mathematical ability, as well as discourses that construct students with LD as having both intelligence and differences such as processing speed. An analysis of interview and observational data suggests that Elijah constructed a unique set of self-understandings as a mathematics learner. Like his sixth-grade special education teacher, Elijah seems to differentiate between knowledge and the performance of knowledge in school. He created a unique identity as both ‘fast’ and ‘slow’ in mathematics, rejecting the binary found in many mathematics classrooms. These findings suggest that multiple discourses circulate in schools about ability and disability in mathematics. 相似文献

This study explores the development of professional identity as a teacher of nature of science (NOS). Our research question was ‘How can a teacher develop a professional identity as an elementary teacher of NOS?' Through a researcher log, videotaped lessons, and collection of student work, we were able to track efforts in teaching NOS as part of regular classroom practice. A team of four researchers interpreted the data through the Beijaard et al. professional identity framework and found that it was not as simple and straightforward to teach NOS as we predicted. Development of professional identity as a teacher of NOS was influenced by contextual factors such as students, administration, and time, as well as personal struggles that were fraught with emotion. Development took place through an interpretation and reinterpretation of self through external factors and others' perceptions, as well as the influence of sub-identities. 相似文献

How teachers become action researchers and how teacher educators become their facilitators 总被引：4，自引：2，他引：2
Petra Ponte 《Educational Action Research》2013,21(3):399-422
The article contributes to the theory of action research by focusing upon kinds of action an individual may undertake in relation to their research endeavour. The article explores action as illusion, as occurring at different speeds according to context, as ‘cure’, as repair to maintain a system, as system improvement, as border skirmishes, as deconstruction and as stealth action. Each of these kinds of action has implications for the action researcher seeking to bring about change. The article explores the ways in which the action researcher can challenge the status quo and bring about creative, educative, democratic frameworks for living in society. 相似文献

Growing and developing as a university researcher 总被引：1，自引：0，他引：1
Gerlese S. Åkerlind 《Higher Education》2008,55(2):241-254
While there is a substantial body of literature on academics’ development as teachers, investigation of their development
as researchers post-PhD is rare. This study undertook an investigation of academics’ ways of understanding their own growth
and development as a university researcher. Four qualitatively different ways of understanding research development emerged:
(1) Becoming confident as a researcher; (2) Becoming recognised as a researcher; (3) Becoming more productive as a researcher;
and (4) Becoming more sophisticated as a researcher. The first category of development was seen as most relevant to the early
stages of an academic career, when doing a PhD or during one’s first academic appointment, but may also re-occur at later
stages of a career during changes in research direction, etc. The last three categories are seen as relevant to all career
stages, including more advanced stages as well as the early stages of a research career. Comparisons between academics’ ways
of understanding their growth and development as a university researcher and as a university teacher are also presented. 相似文献
