“…The results for the openloop/closed loop control and the closed-loop control only are given for the terminal time T' = 0.075. It is noted that the difference in the energy functionals for these two cases depends on the magnitudes of the weighting factors p1 and p2 attached to the penalty functional In Figure 2 the dimensionless penalty functional Ji (see (6a)) and the dimensionless functional Ji involving the maximum values of the deflection and angle of twist (see (8)) are plotted against Ci with Ci = 0 and T' = 0.075. It is observed that the feedback parameter also has an affect on the open-loop penalty functional Ji.…”

“…In practice it is more common to use a displacement actuator than a torsional actuator. However, the energy expression (8) involves both the displacement and angle of twist and the control is exercised on both quantities. From Figure 1 it is clear that the behaviour of the cost functional with respect to the feedback parameter is highly dependent on the terminal time.…”

“…Thus, results on the control of membranes [15], wings [12], beams [16,17], and plates [1,18] became available in the literature. A survey article [22] provides a review of the recent advances in the field of distributed parameter systems.…”

“…Although this situation may lead to excessive vibrations under dynamic loading, the problem can be dealt with by employing structural control, in particular, active control. Applications of this type of control have recently been extended to various structures [1][2][3][4]. Since the idea of active control was first proposed for tall buildings in the 1960s [5], much progress has been made in this field.…”
