Design, realization and control of an innovative electrohydraulic actuator for power systems

The design and realization of an original electrohydraulic actuator making use of metallic bellows are presented. The combination of several bellows allows an electric control to be used in lieu of a compressor, resulting in an easy-to-use and flexible assembly. A platform whose performance is presented in terms of power and frequency of use permits assessment of the overall concept. Experimental results on the actuator are presented.<
