This study investigates the effectiveness of the non-smooth semi-active control algorithm on suppressing the vibration performance of a building structure subjected to seismic waves.According to the Lyapunov stability theory,it has bene proven that the non-smooth semi-active control algorithm can achieve a finite-time stability of the vibration relative to the isolation layer of a building structure.Through numerical simulation of two buildings with different parameters subjected to the input of a seismic wave,the vibration conditions of passive control,LQR semi-active control and non-smooth semiactive control are compared and analyzed.The simulation results show that the non-smooth semi-active control algorithm has a better robustness and effectiveness in restraining the impact of earthquakes on the structure.
