| Summary: | This paper addresses the issue of the impact of controllers in suppressing the vibration of structural building during seismic. It is important to implement an appropriate controller to avoid a huge impact to the building structure from damage and collapse while earthquake occur. Sliding mode controller (SMC) and proportional-integral-derivative (PID) are proposed to alleviate the vibration. SMC is selected as control strategy because of its robust control technique that can reject the disturbances while PID is known as simple control design. The simulation for two storey building equipped with structural control device which known as hybrid mass damper placed at the top floor of the structure that represent by mass, spring and damper are constructed by using Matlab/Simulink. The input excitation to the structure is taken from El Centro earthquake with magnitude of 6.9 Mw. The output response for the system generates displacement, velocity, control input, and frequency response. Based from the result, SMC has better performance compared to PID and overall SMC is success to suppress the building vibration according to the displacement performance obtained. |
