  Nonlinear signal‐based control for shake table experiments

  1 INTRODUCTION Shake tables are crucial for examining the seismic performance of structures and infrastructure 1 2 A structure placed on a shake table is excited by a predetermined signal which is typically a sinusoidal wave or seismic data recorded during past earthquake events Many shake tables are driven by a proportional integration
