Abstract

The dynamic behavior of adaptive trusses composed of active members was studied. The active member contained a displacement-controlled actuator with delayed feedback. The stability condition on the gain for small delay times was found to lie between 0 and 1. The optimal delay time depends on the gain as well as on damping of the structure. A numerical example for a cantilever truss subjected to a dynamic concentrated tip force was presented.
