Abstract : The distributed control of structural systems assumes the availability of highly-integrated, embeddable control elements. Many laboratory experiments in structural control rely upon desktop computers and workstations for convenience, but the size, cost, and power requirements of general purpose computers preclude their use in practical implementations. This study identifies and demonstrates design strategies that facilitate integration of the computational platform with other parts of an embeddable control element. Two specific strategies are explored: the first is the direct application of digital control signals to structural actuators, and the second is a constrained control-law design method that greatly reduces the necessary complexity of the digital subsystem. Each approach results in considerable simplification over the traditional digital control system and contributes to the realization of a truly embeddable element using existing technology.
