Design of a wireless structural vibration control experimental system based on wireless sensor networks

Major progress in developing structural regulators as an important method of vibration control have occurred for the last few decades. Large number of cables that are used in traditional wired control systems can be complicated and expensive. A wireless control system is designed and implemented in this study. Decentralized control strategies are employed in this control system. An optimal control algorithm based on Kalman estimator is embedded DSP controller in the control systems. To validate the performance of this control scheme, a three-story steel structure is developed with active mass dampers installed on each floor. Experimental results show that the wireless decentralized control hsa good control performance and various potential applications in industrial control systems. The designed experimental system may become a benchmark platform to validate the corresponding control algorithm.
