Current controller for active power filter based on optimal voltage space vector
IEE Proceedings - Generation Transmission and Distribution, 2001Co-Authors: J. Zeng, Y. Ni, Q. Diao, B. Yuan, S. Chen, B. ZhangAbstract:An hysteresis current controller for an active power filter based on the optimal voltage space vector is proposed. The controller jointly utilises two sets of phase current difference comparators to determine the location region of the reference voltage space vector and the current error space vector. When the system reference voltage space vector is changing rapidly and randomly, which makes its location region very difficult to estimate, the novel controller can quickly detect its location region by a trial-and-error process which is essential to the performance improvement of active power filters. The Related Concept and formulation are presented. A computer simulation is conducted on a test system and the results show that the controller can quickly determine the optimal voltage space vector, therefore effectively reducing the current tracking error. Since the new controller can reduce VSI switching frequency, it can reduce the switching loss and improve APF efficiency noticeably.

A novel current controller for active power filter based on optimal voltage space vector
Proceedings IPEMC 2000. Third International Power Electronics and Motion Control Conference (IEEE Cat. No.00EX435), 2000Co-Authors: J. Zeng, Y. Ni, Q. Diao, S. Chen, B. ZhangAbstract:In this paper, a novel hysteresis current controller for active power filter based on the optimal voltage space vectors is suggested. The controller jointly utilizes two sets of inter-phase current difference comparators to determine the location region of the reference voltage space vector and the current error space vector respectively. When the system reference voltage space vector is changing rapidly and randomly which makes its location region difficult to be estimated, the novel controller can quickly detect its correct location region by one trial-and-error process which is essential to the performance improvement of the active power filter. The Related Concept and formulation are presented. Computer simulation is conducted on a test system and the results show that the controller can quickly determine the optimal voltage space vector, therefore current tracking error is reduced effectively. So the voltage source inverter (VSI) switching frequency can be reduced and the efficiency of active power filter (APF) can be improved apparently under the same control accuracy.

Cross-border transfer of a systemic Mobility-as-a-Service -Related innovation
ISPIM Innovation Symposium, 2017Co-Authors: Tero J Haahtela, Teemu J Surakka, Esa I Viitamo, Johannes Asamer, Martin ReinthalerAbstract:Mobility-as-a-Service (MaaS) is an emergent service Concept aimed to provide knowledge-based solutions for sustainable transport. We investigate the transferability of a MaaS-Related on-demand shared taxi service from one cultural and geographical context to another using in-depth case study method. To provide insights on transferability, we compare an Austrian MaaS-Related Concept, ISTmobil service, with three other new similar kinds of on-demand transport service Concepts: the Finnish Kutsuplus and Kyyti and the multinational UberPOOL. We apply the socio-technical framework of Geels in the analysis and examine how legislation, culture, technology and policies influence the adaptation of the chosen MaaS-Related service elsewhere. We also discuss the applicability of Geels' framework in analysing the transferability of this Concept. This research is conducted in the on-going ENSCC Smart Commuting project.

social influence and contextual utilization of customer relationship management technology in an international field sales organization
Journal of Relationship Marketing, 2014Co-Authors: David S. BakerAbstract:Building from Related interdisciplinary theories, this research identifies social influence–Related variables that are linked to customer relationship management (CRM) technology utilization within an international business-to-business field sales force. Field sales employees (n = 147) in a multinational organization from Australia, Canada, New Zealand, the United Kingdom, and the United States were surveyed to test the research model. Four of 7 primary hypotheses were supported, predicting more than 65% of the variance in the research model. Effort expectancy, uncertainty avoidance, collective performance expectancy, and internal/organizational social influence all showed antecedent significance to contextual utilization of CRM technology. The results of this study suggest that group-oriented individual decision making and the Related Concept of institutional collectivism are equally as important as individual-oriented decision making in the international utilization of organizational technology.

Social Influence and Contextual Utilization of Customer Relationship Management Technology in an International Field Sales Organization

The results of this study suggest that group-oriented individual decision making and the Related Concept of institutional collectivism are equally as important as individual-oriented decision making in the international utilization of organizational technology. Based on the strong significance shown in the results of this study, it would also be wise to consider cultural value–derived uncertainty avoidance in practical development of training and implementation of multinational CRM systems.
