Paper Abstract

This paper describes an approach for designing a structure-control system based on the linear quadratic regulator (LQR) which suppresses vibrations in structures. Bounds are placed on the control forces to simulate real actuators. The control system is optimized with an objective function of the time to reduce the energy of the vibrations to 5% of its initial value. The design variables are the bounds on each control force with a constraint on the sum of the bounds. As an example to illustrate the application of an approach, a wing box idealized by rod elements is used. Control systems are designed for this structure using four and eight actuators for several locations.
