Adeli 2004), and various control strategies have been proposed, such as sliding mode control (Edwards and Spurgeon 1998) and optimal polynomial control (Agrawal and
Yang 1996). However, most of the studies have focused on the application of classical
linear control theories such as linear quadratic regulator (LQR) feedback control algorithm (Soong 1990) and linear quadratic Gaussian (LQG) control algorithm (Stein
and Athans 1987). These algorithms control structural responses effectively only when
the structure is small and assumed to behave linearly.
