永磁同步电机的干扰观测器补偿与模糊切换控制

A PMSM speed control algorithm combining disturbance observer compensation and fuzzy integral sliding mode control (DOB+FISMC) was proposed to solve the problems of slow starting response speed and weak anti interference ability of PMSM speed regulation system. The PMSM speed control model with uncertain interference was established, and the equivalent integral sliding mode control of fuzzy switching was proposed. To reduce the switching gain of FISMC and improve the control accuracy, a disturbance observer was designed to compensate the total interference. The effectiveness of the control algorithm was verified based on the PMSM speed regulation system simulation model. The results show that, compared with the traditional proportional integral control (PI) and sliding mode control (SMC), the proposed algorithm has less tracking error, faster response and stronger resistance to interference for a given sinusoidal signal. This algorithm can improve the starting response speed and robustness of permanent magnet synchronous motors.     

实用艺术作品的法律保护

目前,我国对于实用艺术作品的认识不统一,缺少深入的系统研究,相关法律规定也不够完备,不尽合理。实用艺术作品是指同时具有实用性和艺术性特征,具有独创性、能够被有形复制的造型艺术作品。对实用艺术作品既可以采用著作权进行保护,也可以采用工业外观设计权进行保护,权利保护模式由当事人进行选择,选择了一种权利就意味着放弃了另一种保护模式。     

Atypical Working Hours: Consequences for Childcare Arrangements

This paper analyses the care arrangements of those dual‐earner couples and lone‐parent families who are under strong pressure because of atypical and unpredictable working hours. In these situations, the parents have to invent day‐to‐day, week‐to‐week solutions for the care needs of their children, mobilizing all available formal and informal resources. The objective is to understand the different ways in which families manage such atypical working hours in three different countries (Finland, France and Portugal). What are the main strategies of the parents in facing this pressure? Do these include negotiations between the parents on the division of tasks, mobilization of ex‐partners, grandparents, brothers and sisters, neighbours, and the different solutions offered by the formal resources? In the first part of the paper, we present the challenges and consequences of atypical working hours for families and institutions in Europe, in particular in Finland, France and Portugal. We then analyse some of the childcare arrangements as well as the impact of the provision of childcare services.

Proxy reporting in education surveys: factors influencing accurate reporting in the 2012 Qatar Education Study

Abstract

Proxy reporting is a common practice during survey data collection to increase response rates while reducing fieldwork costs, and agreement between proxies and self-reports is critical to make reliable and valid inferences. This study is the first to unpack what influences proxy accuracy in a non-Western setting using data from the 2012 Qatar Education Study. We find that agreement is a function of a student’s grade in school, grades, a parent’s level of education, and the interaction between immigration status and parent education. These findings suggest in multicultural contexts, agreement may vary based on factors beyond what is typically accounted when examining the components of reporting error as a result of using proxies over self-reports.
