چکیده
This study explores decentralized structural control using wireless sensors and controllers. In a decentralized control scheme, control decisions are based upon data acquired from sensors located in the vicinity of a control device. Specifically, this paper studies a time-delayed decentralized structural control strategy that aims to minimize the H2 norm of a closed-loop control system. For decentralized control design, one challenge is the non-convexity of the optimization problem caused by a decentralized architecture. Genetic algorithm, which has a stochastic search mechanism and does not require problem convexity, is explored in this research for designing decentralized structural controllers with minimal closed-loop H2 norm. Multiple decentralized control architectures are implemented with a network of wireless sensing and control devices. The wireless sensing and control system is installed on a six-story laboratory steel structure controlled by magnetorheological (MR) dampers. The sensor network supports simultaneous communication within multiple wireless subnets. Experimental tests are conducted to demonstrate the performance of the wireless decentralized controllers optimized with genetic algorithm.
