Abstract

Today, the care and welfare pneumatic equipment to support a nursing care and a self-reliance of the elderly and the disabled are actively researched and developed by many researchers. These wearable devices require many servo valves for multidegrees of freedom and precise control performance of the wearable actuator. The total weight of the wearable devices increases according to the degree of freedom. In our previous study, a small-sized and lightweight pressure control- type quasi-servo valve was developed t. The valve consists of two on/off control valves and an embedded controller. In this study, the quasi-servo valve composing of much smaller-sized (40% in mass, 42% in volume) on/off valves is proposed and tested. The analytical model of the tested valve is proposed and the system parameters are identified. As the result of the comparison between experimental results and simulated, it was confirmed that the proposed analytical model and the identified system parameters were valid.
