“…In the field of vibration suppression of piezoelectric smart structures, many types of control schemes have been proposed and developed during the past few decades. For example, traditional control methods like negative velocity feedback control [4][5][6], positive position feedback control [7][8][9][10], PID control [11][12][13][14] and bang-bang control [15][16][17]; modern control methods such as Lyapunov control [18,19], linear quadratic regulator (LQR) control [18,[20][21][22] and linear quadratic Gaussian (LQG) control [20,[23][24][25][26]. There are also some advanced control and intelligent control methods which can be found in the literature, for instance, sliding model control [27,28], model predictive control [29,30], fuzzy logic control [31,32] and neural network control [33][34][35].…”
