This paper describes optimum posture determination of variable geometry truss structures by optimality criteria method. A minimum compliance posture of variable geometry trusses for a given working load vector is realized by adjusting variable elements, where the adjusting control values are determined independently according to optimality criteria transformed from strain energy equation in advance. The validity of optimum posture determination by optimality criteria is confirmed numerically by applying it to the configuration control of a pair of variable geometry trusses containing ten adjustable elements for cooperative work.
