With the development of wireless technology, active structural vibration control based on wireless sensor network has possibly tended to replace the traditional wired control method to an extent. Compared with wired control, wireless control has the characteristics of low cost, flexibility and easy implementation. In this paper, in order to further improve the flexibility and robustness of the wireless control system, the three-layer steel structure model is designed as the research object, the fuzzy PID control algorithm is developed, the high flexibility DSP is used for the controller, and the distributed wireless control experiment is done finally. The experimental results show that the fuzzy PID control algorithm can restrain the vibration of the structure well under the given initial state and earthquake excitation, and that the developed wireless distributed control experimental system is validated and has various potential applications in industrial control systems.
