In this study, position controller designed in the using long transmission line for contrlling pneumatic cylinder apparatus. This apparatus form pneumatic cylinder, control valve, detected pressure and position sensor, transmission lines. In controlling pneumatic cylinder apparatus , short transmission lines don't have an effect on arround system and damping ratio, but long transmission line influence on system characteristic because of line characteristic. In the study, on that score, design position controller, inspect propriety of designing controller.

In this study, we are to analyze the life and the main failure mode of parallel opening type pneumatic chuck that are usually applied in the factory automation line. Pneumatic chucks have complicated failure cause because they are organized as a complex of various elements. Therefore, in this paper, we analyzed the main failure mode of pneumatic chuck, and then performed life test and performance test according to the international standards. On the basis of these processes, we estimate shape parameter that is the main factor for the calculation of test time for the reliability of pneumatic chuck and their data analysis of life distribution.

Pneumatic driving systems have a hard non-linear characteristics and a large friction force compared with driving power. Hence, it can not be robust against parameter uncertainties, modelling error, disturbance and noise. In this study, we apply a mixed H₂/H∞ control to the generalized plant for a pneumatic driving apparatus system involved parameter uncertainty and disturbance. In order to design the H₂/H∞ controller, we use the LMI technique. To evaluate control performance and robust stability of designed controller, we compare it with the conventional controller(PVA controller) using the simulation results. As a result, it can be know that designed controller shows the better robust stability than the conventional controller.

본 논문은 근수축을 이용한 근육 작용의 운동학을 다룬다. 첫째, 근육 해부학이 미시적 관점의 운동학에 대하여 검토되었으며, 다음으로 거시적 관점의 근육 운동학이 작동 이론을 설명하기 위해 공식화 되었다. 그리고 작동 모델을 평가하기 위해 시뮬레이션 결과가 제시된다. 본 연구는 마이크로미터 거리에 따 라 생물학적 분자 운동이 어떻게 거시적 운동으로 바뀌는지를 설명하고 있다. 마지막으로 근육 모델이 거시적/미시적 작동용으로 여러 가지 역학의 형태로 이용될 수 있다는 것을 보인다.

Pneumatic system is widely applied in various industry because it have a many advantage(low cost, high safety, etc..). For design of pneumatic system, accurate flow measurement is required. In this study, compressible fluid flow measurement apparatus was designed and built. It uses an isothermal chamber that can approximate isothermal condition. Therefore, it can be measured for flow-rate using pressure response of isothermal chamber. As a result, this apparatus can be measured for sonic conductance and critical pressure ratio of pneumatic components and it required less time and energy than conventional flow meter. The effectiveness of the designed apparatus is proved by experimental result.
