| Abstract: | In this paper adopt the harmonic superposition method, simulate transmission tower of fluctuating wind velocity time-history curve and wind load time-history. Introduce the principle of LQR control algorithm, and make the procedure of the LQR control algorithm using MATLAB language, the transmission tower mode is analyzed to gain the control effect of the structure under wind loads. Structure shows that the LQR control method can reduce the wind vibration response of transmission tower effectively, and the LQR control method is a kind of rather ideal damping method. |
