IPMSM 드라이브는 하중 비에 대한 출력이 우수하여 전기자동차 등 응용분야에서 관심이 증가하고 있다. 이러한 응용분야에서 최대 효율을 얻기 위하여 본 논문은 신경회로망 제어기법을 제시한다. 동손과 철손으로 구성된 제어가능한 전기적 손실은 신경회로망의 오류 역전파 알고리즘(EBPA)를 이용하여 최소화시킬 수 있다. 손실의 최소화는 IPMSM 드라이브의 효율 최적화 제어를 가능하게 한다. 본 논문에서는 신경회로망의 EBPA플 이용하여 전동기 구동에 대하여 d축 인덕턴스, 전기자 저항, 역기전력 상수 변화와 같은 파라미터 변동을 실시간으로 계산하여 고성능 및 강인성 제어를 제시한다. 제시한 알고리즘은 IPMSM 드라이브 시스템에 적용하고 효율최적화 제어에 의해 제어된 동작특성을 분석하여 논문의 타당성을 입증한다. Interior permanent magnet synchronous motor(IPMSM) has become a popular choice in electric vehicle applications and so on, due to their excellent power to weight ratio. To obtain maximum efficiency in these applications, this paper proposes the neural network control method. The controllable electrical loss which consists of the copper loss and the iron loss can be minimized by the error back propagation algorithm(EBPA) of neural network. The minimization of loss is possible to realize efficiency optimization control for the IPMSM drive. This paper proposes high performance and robust control through a real time calculation of parameter variation such as variation of back emf constant, armature resistance and d-axis inductance about the motor operation. Proposed algorithm is applied IPMSM drive system, prove validity through analysis operating characteristics controlled by efficiency optimization control.

The purpose of this study is to present possibility for understanding and development of sport behavior by re-interpreting the morality of sport behavior showed the aspect of physical education and sports. Moral responsibility in sports behavior can be found in self-relation, others-relation and relation between self and society. Obligation in sports behavior occurs when they believe each other and it becomes a characteristic. To observe regulations are general promise in sports society. Therefore spectators, referee and counterpart requires to keep the promises and they believe the other man must keep the promises. The promises is a truthful contraction and basic obligation of sport behaviorist. Faith in sports behavior is connected with responsibility, the conscious, custom, betrayal and also understood in concerns with personality. Personality is a dynamic organization of psychology·physiology system and means to determine human behavior and consideration about circumstances which is surrounding human. Therefore personality means self-awakening present will and future will which intends self-conservation. Sports behavior is a learning process of self-actualization and active self-accomplishment. Therefore sports behavior request to include endeavor of human behavior and it is an self-behavior in truthful meaning.
