Özet
In this study, linear quadratic regulator (LQR) and fuzzy logic (FL) controller are designed for displacement control of elastic structure under seismic excitation. MATLAB (R)/SIMULINK toolbox is used for the mathematical modelling of the system and controllers design. Controllers are applied to the structure, components of which are assumed that they have standard stiffness and damping coefficient, to suppress seismical vibration. A hydraulic actuator is used as the control device. Dynamic of the actuators to create the control force to be applied to the structure, involved in the equation of motion of the controlled structure. The equation of motion of the system obtained in state-space model in continuous time is converted to discrete time. The equation of motion of a real building model structure is solved and simulated by using the data of a known earthquake having occurred ago. Numerical simulations and vibration results of the LQR and FL controlled and uncontrolled structure are presented in the form of graphics.
