PHASE DELAYED OPTIMAL ACTIVE CONTROL OF STRUCTURES UNDER STOCHASTIC BESE EXCITATION WITH A PREDOMINANT FREQUENCY

抄録（英）：
Phase delayed acitive control of structures under stochastic base excitation is investigated. The synthesis of an active control system discussed in the study is based on the use of stochastic control theory, where an energy-based stochastic criterion is employed for optimal control. As a result, an optimal control law for input with a predominant frequency is developed, which consists of a reponse feedback portion and a ground-input feedforward portion. The effectiveness of the phase delayed active control law is demonstrated with a numerical simulation, which shows that the proposed control law brings considerable control force (RMS) reduction, compared with the feedback control, when the two have the same level of reponse reduction. However, if phase lag becomes more than one-third of the natural period of structures, efficiency of the control force decreases rapidly.
