This paper is concerned with the design of linear matrix inequalities based
2 HH ¿ mixed state-feedback controller design for seismic excited asymmetric structural systems having stiffness irregularities. A one storey, two way
asymmetric structural system model is used to illustrate the effectiveness of approach through simulations. The modelled system has bi-lateral and a rotational degrees of freedom. Frequency responses show the superiority of proposed mixed controller against H2 and H¿ controllers. Moreover, the
time domain simulation results, acquired by using real time history data of El Centro Earthquake also shows that proposed controller is very effective in reducing vibration amplitudes of each direction by applicable control signals and guaranteeing the stability of closed loop system
