EXPERIMENTAL-VERIFICATION OF BOUNDED-FORCE CONTROL METHOD

An efficient and simple non-linear active control method called Bounde d-Force Control (BFC) method has been developed. The theoretical devel opment and application examples of the BFC method has been presented i n several publications(1-3) where it was shown that the BFC is more ef ficient than the Linear Quadratic Regulator (LQR) method in terms of m aximum control force and power requirements when applied to an Active Tuned Mass Damper (ATMD) system. Following a brief review of the funda mental concept of the BFC and a discussion of its main advantages, the results of an experimental investigation using a three-storey shear b uilding model excited by a shaking table and controlled by an electrom agnetic linear motor are presented. The experimental results were in p erfect agreement with the analytical results, thus confirming the vali dity of the proposed BFC algorithm.
