  • This paper presents intelligent digital redesign method of global approach for hybrid state space fuzzy-model-based controllers. For effectiveness and stabilization of continuous-time uncertain nonlinear systems under discrete-time controller, Takagi-Sugeno(TS) fuzzy model is used to represent the complex system. And global approach design problems viewed as a convex optimization problem that we minimize the error of the norm bounds between nonlinearly interpolated linear operators to be matched. Also by using the power series, we analyzed nonlinear system's uncertain parts more precisely. When a sampling period is sufficiently small, the conversion of a continuous-time structured uncertain nonlinear system to an equivalent discrete -time system have proper reason. Sufficiently conditions for the global state -matching of the digitally controlled system are formulated in terms of linear matrix inequalities (LMls). Finally, we prove the effectiveness and stabilization of the proposed intelligent digital redesign method by applying the chaotic Lorentz system.

  • Purpose - The present study theoretically reviews the use of power norm according to the cultural orientation of consumers to categorize the shopping value that corresponds to the use of the power norm when consumers use local food stores. Research Design, Data, and Methodology - Based on the data collected from the survey to 130 undergraduates, salaried men and people at large, the group with cultural value orientation was divided further into the group of horizontal individualism and that of vertical collectivism by using cluster analysis of SPSS 18.0 program. And regression analysis of SPSS 18.0 was employed to verify the hypotheses. Results - The following conclusions were shown in the empirical study. First, in the group of vertical collectivism, contribution to regional profits and competitiveness, economic value and service superiority can positively affect the attitude to the local food stores while the social responsibility activity in the community can't. In the group of horizontal individualism, however, contribution to regional profits and competitiveness, social responsibility activity, economic value and service superiority were all found to positively affect the attitude to the stores. Second, the distinctive shopping value of the stores such as escapism, entertainment value and prestige does not affect the attitude to the stores. Third, the positive effects that the stores' level of responsibility for the outgroup community can exercise on the attitude to the stores turned out to be bigger in the group of horizontal individualism than in the group of vertical collectivism. Fourth, the impact that the degree of the stores' contribution to regional profits and competitiveness has on the attitude to the stores was found to be positive in both groups. However, no difference existed in the degree of positive effects between them. Conclusions - Marketing managers of local food stores should pay more attention to managing their contribution to practical shopping value and to interests as well as competitiveness of regional society, and to persuading consumers of the horizontal individualistic group by performing responsible activities for the outgroup of local society regardless of the types of consumers' cultural orientation.

  • 본 논문은 복합 상태 공간에서의 피지 기반 제어기를 이용한 지능형 디지털 재설계의 전 역적 접근 방안에 대해 제안하고자 한다. 이산화를 통한 제어기 설계에 있어서 불확실성이 포함된 실시간 비선형 시스템에 대해 보다 효율적이고 안정적인 접근을 위해 TS 퍼지 모델이 사용되었다. 그리고 전 역적 접근을 위한 방안으로서 문제를 볼록 최적화 관점으로 변환 후, 에러가 가질 수 있는 놈의 영역을 최소화하여 상태 접합을 이루고자 하였다. 또한 power series를 사용함으로써 불확실성이 조합된 비선형 시스템을 보다 더 정확하게 분석하였다. 샘플링 기간이 충분히 작다면, 불확실 비선형 시스템의 실시간 시스템으로의 전환이 충분한 이유를 가지게 된다. 전 역적 접근을 통한 디지털로 제어된 시스템은 선형 행렬 부등식 형태로 바꾸어 시스템의 안정성을 보장하고자 하였다. 마지막으로 TS 퍼지 모델로 분석된 혼돈 Lorenz System에 적용함으로써 제안된 방법의 안정성과 효율성을 보장받게 된다.
