Identification of critical parameters in active control schemes for optimal structural control
https://orcid.org/http://orcid.org/0000-0003-2020-2964
Active control schemes are quite promising because of their capability of achieving high level of control of structural response under seismic excitations. Level of control is a function of many parameters associated with structure, excitation and the scheme of control considered. Optimal level of control may be achieved by optimization of control parameters. Basically, elements of weighing matrix primarily govern the relationship of control force and the level of response reduction. But which parameters are predominant in governing this relationship is the matter of investigation. Weighing element associated with velocity of actuated tuned mass damper has been chosen by some researchers as an important parameter in case where force actuation was done through an active mass driver system. But other elements of weighing matrix need to be investigated with a possibility of being predominant in controlling the response. An extensive parametric study is needed to arrive at the best combination of parameters that may lead to the optimal structural control. Keeping in view the same, an effort is made here by trying various combinations of the different elements corresponding to displacement and velocity terms of the state vector to obtain the optimum level of control of structural response with a least possible level of control force.
