| Abstract: | This paper addresses the pursuit of robust hybrid control for seismically excited structures, employing structural models featuring devices such as Viscous‐Fluid‐Dampers integrated with Chevron bracing, Base‐Isolators, and Active‐Controllers, utilized in passive, active, and hybrid control configurations. Motion equations were formulated in state space, facilitating simulations to assess nominal performance. Primitive parametric uncertainty was defined to ascertain stability and performance margins of passive control systems. Robust parameters of the selected control system were determined, followed by the derivation of maximum parametric uncertainty ranges and the design of an Hꝏ‐based active controller for an uncertain Closed‐Loop system. Time histories of floor displacements, damper force, and active controller power were analyzed. Our examination revealed that parametric uncertainties vary based on the type, physical characteristics, and placement of passive control devices. In robust controlled systems, the utilization of an active controller significantly reduced the reliance on passive control equipment, while non‐robust systems exhibited divergent seismic behaviors. Overall, the results demonstrate the effectiveness of hybrid control strategies in mitigating seismic responses, with the incorporation of base isolators extending the range of parametric uncertainties.
