    Abstract

    Non-linear model-based controller design enables high bandwidth motion control of servohydraulically actuated systems. In this paper, results are presented for three example systems from the structural testing industry: a pedestrian impact test system, a crash testing catapult, and an earthquake simulation table. An important element of such control systems is the provision of high accuracy, low noise feedback signals (for example combining position and acceleration measurements to improve motion estimation). Closed loop bandwidth well above the hydraulic resonant frequency is achievable.
