Dynamic response and vibration control of tensegrity systems under seismic excitation
Abstract eng: The present study focuses on applying a relative validate and efficient control strategy to the seismic vibration control for tensegrities. In order to restrain deflections, maintain shape, and ensure that the structural shape is always optimal for the current loading the Linear-Quadratic Regulator (LQR) is adapted for implementing the active control approach. Additionally, the response of the aforementioned system is evaluated by considering different actuator placements. This includes: struts, cables and combination by change their positions in different region such as inner to outer. A numerical example is given to demonstrate the efficiency of the investigated approach. Planar tensegrity beam comprising of two modules, with pretension 30 cables and 8 struts with piezoelectric actuators, is optimized with the maximum system response for all simulated scenarios. The outcome of the proposed study highlights the significant reduction of dynamical response compared to the uncontrolled performance. The obtained results indicate that the actuator placements have a great potential and deserve further investigation.
