Abstract: In radiation contaminated area sensors have high risk of malfunction, and human cannot work in this area.Therefore, master and slave system without sensors is needed. In this paper, the reaction force estimation for hydraulic system is evaluated. Previously, estimation of reaction force using sliding perturbation observer has been applied to electric motor system. However, hydraulic system has different elements which are uncertain parameters such as compressibility and viscous friction from electric system. …
