유압 밸브-모터 시스템의 불확실성에 대한 $H_{\infty}$ 제어
The $H_{\infty}$ control of the uncertainty for the hydraulic fluid valve-motor system
초록
This study describes a hydraulic fluid property compensator under the various operating conditions. Because hydraulic fluid systems have much more excellent features than other control systems, they are used in many fields. However, the characteristics of hydraulic fluid are changed due to various operating conditions. This phenomenon is called uncertainty. Especially, bulk modulus is considered as the most dominant parameter in this study. Under the wide range of temperature and pressure, bulk modulus is changed. In order to overcome the uncertainty,
