Performance Examination of Nonlinear Signal-Based Control in Shake Table Experiments with Sliding Structures

This study examines nonlinear signal-based control (NSBC) in shake table experiments with sliding structures, which have an isolation effect during earthquake. NSBC uses a signal obtained from the outputs of controlled system and its linear model under same input. Owing to presence model, controllers are described by transfer functions, even for controlling systems. achieved excellent specimen having characteristics such as yielding structural components. A structure placed on significantly jeopardises because severity is greater than yielding, compensation has not yet been fully developed. Therefore, this introduces into structures along design enhance their robustness, utilising analysis stability evaluate design. Numerical simulations friction coefficient 0.22 demonstrate performance acceleration control. However, inversion-based (IBC), basic approach, shows ineffectiveness. In actual 0.2, reasonable almost 100% accuracy, whereas IBC was ineffective. clarifies that can solve problem degradation caused table.
