Summary

Experimental investigation of structural control strategies is an important stage in structural seismic design. Shaking tables are powerful instruments for verification of control strategies implemented in civil structures subjected to earthquakes. In this work a well-known pole-assignment method is used to determine the active mass damper (AMD) control law parameters. The design procedure is computerized using subroutines, written in MATLAB. Close-loop system poles assignment is based on accurate approximation of the open-loop system's transfer function. A practical identification algorithm for such approximation is developed. It is realized in MATLAB and SIMULINK routines. The algorithm automatically performs the experiments and calculates the investigated system transfer function parameters. The AMD controller is designed and verified using the proposed technique. The controller represents an output feedback, including the asymptotic observer for state vector estimation as a function of the AMD's relative position measurement, and the full state feedback, assigning the desired poles of the close-loop AMD-structure system.
