EXPERIMENTAL VERIFICATION OF BOUNDED-FORCE CONTROL METHOD

An efficient and simple non‐linear active control method called Bounded‐Force Control (BFC) method has been developed. The theoretical development and application examples of the BFC method has been presented in several publications where it was shown that the BFC is more efficient than the Linear Quadratic Regulator (LQR) method in terms of maximum control force and power requirements when applied to an Active Tuned Mass Damper (ATMD) system. Following a brief review of the fundamental concept of the BFC and a discussion of its main advantages, the results of an experimental investigation using a three‐storey shear building model excited by a shaking table and controlled by an electromagnetic linear motor are presented. The experimental results were in perfect agreement with the analytical results, thus confirming the validity of the proposed BFC algorithm.
