Structural control systems in high-rise and complex buildings encounter some problems, including reduced system reliability, increasing communication requirements, and longer latencies in the feedback loop. To address these issues, one accepted solution is using independent control algorithm that work autonomously. In this way, each system is decomposed to several uncoupled subsystems, and each controller associated with a specific subsystem only uses local information to determine the control command of that subsystem.
In this paper, a new decentralized control algorithm for large-scale civil structures is developed from the simple adaptive control method. The resulting direct adaptive control methodology is referred to as decentralized simple adaptive control (DSAC).
Using MATLAB and SIMULINK a numerical solution was conducted on a 3-story and a 20-story benchmark buildings under seismic excitations. Comparing the results of numerical simulation employing DSAC, with control criteria by the conventional centralized (SAC) approach, demonstrates the feasibility of the proposed decentralized control method using active dampers. Moreover, control performance using MR dampers are presented for the 3-story and 20-story structures. Then the performance of decentralized simple adaptive control system is compared with the conventional simple adaptive control approach when MR dampers are in use. It is shown that decentralized control strategies may provide equivalent or better control performance, given that their centralized counterparts could suffer from longer sampling periods due to communication and computation constraints.
