Based on the proposed new type of piezoelectric friction damper , a finite element model of a high-voltage transmission tower was established with the finite element software ANSYS .Meanwhile , the overall stiffness and the quality and damping matrixes of the transmission tower structure were extracted by combining the super -element method and MATLAB programming .The LQR optimal control strategy and the Bang-Bang optimal semi-active control strategy program were compiled , and a suitable semi-active control system for the high-voltage transmission tower was established by combining the two strategies with the SIMULINK toolbox .With the proposed piezoelectric friction damper and the preparation of the semi-active control system , vibration control was carried out towards the transmission tower under the conditions of the EL-Centro earthquake .The results show that the damper and semi-active control system can effectively control the seismic response of the tower and the averaged control effect coefficient reached 25%.
