title = "Estimation of pressure control performance in low-cost quasi-servo valve using embedded controller",
abstract = "In our previous study, a small-sized and light-weight pressure control type quasi-servo valve was developed to reduce the burden of the user in a powerassisted system. The valve consists of inexpensive on/off control valves and embedded controller. In this study, the pressure control performances using four kinds of control scheme were investigated and compared by experiment and simulation. The frequencies up to 5 Hz were applied to the tested pressure control system. As an index of control performance, we used the mean absolute error. As a result, the sliding mode controller gave smaller error on the whole and PD controller gave the good performance in the higher frequency. It was confirmed that the introducing the dead zone to a control input and the lowering the supply pressure were effective to suppress the impulsive pressure change.",
