LMI BASED MIXED H2/H∞ STATE-FEEDBACK CONTROL OF CRANE STRUCTURES AGAINST EARTHQUAKE INDUCED VIBRATION

41547

This paper deals with the active vibration control of cranes against earthquake induced vibration. For this purpose, firstly a dynamic model is developed and then Linear Matrix Inequalities (LMIs) based mixed H2/H∞ state-feedback controller is designed in this study. Performance of the designed controller and active vibration control system is investigated by simulation. The time history of ground motion of the Marmara Kocaeliearthquake in 1999 (Mw=7,4), which is a disturbance input, is applied to modeled container crane. Additionally, the performance of the designed controller is also compared with a state-feedback H∞ controller. Simulation results indicate that superior earthquake induced vibration suppression is achieved by the use of designed controllers and active vibration control system.
