Simulation Analysis of PID Vibration Control of Cables Using Giant Magnetostrictive Actuators
摘要
Abstract
Large amplitude vibration of stay cables can bring a great threat to the operation of the cable-stayed bridge. Using axial force provided by a giant magnetostrictive actuator (GMA) is a feasible method for cable vibration suppression. In this paper, the dynamic model of the GMA is established. And the actuator’s force-displacement function is obtained. Then, the PID control algorithm of the stay cable and the GMA coupling is proposed. Finally, simulation analyses of the stay cable under free vibration, harmonic excitation and random excitation are carried out. The result proves that the vibration of the cable can be controlled effectively by PID control algorithm.关键词
