Structural sparsity in control design of active and semi‐active systems

Civil building structures equipped with active or semi-active control devices help mitigate structural damages in the presence of any seismic excitation. These advanced mitigation systems require additional such as sensors, actuators, and communication that increase issues related to energy consumption, measurement errors, costs implementation. In this work, we propose a methodology based on concept sparsity induce sparse pattern feedback system takes into account prior information inherent relationship between variables controller. This can potentially decrease implementation while keeping suitable performance structure when subjected external disturbances. We show through mathematical analyses simulation results benefits using proposed both systems.
