The EHA design involves 2 channels arranged in a tandem force-summing configuration, which needs a detailed study of the redundant EHA in the active/active mode, as well as in the passive mode. Thus, the research addresses the characteristics difference between the dissimilar power modules. A cooperative control method is proposed to manage the force equalization and the pressure transients.
