Control strategies for a slender structure

Résumé

In this study we start from a modelization by finite elements of a 150 m high tower and try to introduce various control scenarii into the model. The model is realistic in terms of orders of physical size for masses, stiffnesses and other geometrical and mechanical data. We hope to compare control strategies on this model. Each of the control process is compatible with a technological achievement (e.g dampers). The control is provided by actuators that must be located in the building. We compare the energies to get in each control type and the reached efficiency. The global target is to find out a control law model technologically transposable to an actual structure and to define the best control strategy, i.e. to find out the best compromise between the energy to be provided, the reducing in vibratory levels, the actuator location and the actuator operating safety. These elements could be defined as "control criteria". Among the several possible sollicitations, we will focus on seism-type sollicitations and will define the actuators location in relation to the building architecture. We will simulate the building behaviours with and without control and will compare the results in terms of vibratory level reductions and energies at work.
