Hoseo University is a private Christian university in Asan, South Korea, known for its large size, 3.471074 km2. It was the first school to establish a graduate school for venture business in South Korea.The university's "World Class 2030" project promotes research in the area of unexplored fields such as the interface of five senses, the expression of the sense of smell, or defense mechanism of invertebrate animals within 20 years.The university was originally a private technical college when it was founded in 1978 in Anseo-dong, Cheonan-si, Chungcheongnam-do, called Cheonwon Technology University. The founder is Seokgyu Kang, and the motto of the school is "We can do it, and it will come true." In 1980, Cheonwon Technology University changed its name to Hoseo University and, in eight years, it was re-formed as a four year collegiate university. The second Hoseo University campus was founded in 1989 in 165, Sechul-ri, Baebang-myun Asan-si, Chungcheongnam-do. The administration facilities of the university were moved to the second Campus in Asan, making the Asan campus the main campus of Hoseo University, and Cheonan campus automatically became the first campus in 1991. The university has a central library, museum, broadcasting company, newspaper, continuing education and health clinic center, etc. It also has several research centers: industrial-educational cooperation research center, small and medium sized businesses research center, industrial technology research center, display technical education research center and environmental bio research center.

In the paper, an output-based disturbance observer of reduced order is presented for a class of discrete-time linear systems. First, a general form of a disturbance observer is proposed when full states are available. Then, by combining a state function estimator of minimal order, an output-based disturbance observer is derived. The existence condition will be formulated in the form of a static output feedback. Through examples, the effectiveness and advantages of the proposed approach will be demonstrated. A servo control problem in practice is addressed to show the validity of the approach. Furthermore, it will be shown that the proposed approach does provide a smaller order of disturbance observer than that of conventional approaches, while maintaining satisfactory performances. © 2013 Elsevier Ltd.

This paper presents several of the problems encountered with vector-controlled single-phase induction motor (SPIM), and discusses about the complex implementation of a vector controlled SPIM drive. The vector-controlled symmetrical two-phase induction motor (TPIM) is presented as a viable replacement for the vector-controlled SPIM. The implementation of the proposed vector-controlled TPIM is simple compared to the vectorcontrolled SPIM. All the TPIM parameters can be calculated simply and precisely. The proposed strategy for TPIM is derived from the indirect vector control strategy used for three-phase ac machines. Several differences between the vector control strategies for the TPIM and for three-phase ac motor are discussed. The validity of the proposed vector-controlled TPIM was verified by simulations and experiments. © 2012 IEEE.
