This paper aims to find the optimal sensor locations on the bases of unified control system to minimize the observation cost while satisfying accuracy requirements of system performance for cable-stayed bridges. A new optimal sensor-location algorithm was developed using output feedback of unified control concept which can reduce observation cost associated with constrained observability matrix. This proposed algorithm was applied to the four degree of freedom structural system which contains the same complexity and structural characteristics as a cable-stayed bridge. It also proved to be useful to choose the best sensor location for controllability and observability of the structural system.
