“…In the work by Liu et al, 10 a joint control method of boundary control and iterative learning control based on finite dimensional backstepping control and Lyapunov direct method was proposed for vibration suppression of nonlinear flexible riser system affected by external disturbance. In the work by Liu and colleagues, 11,12 adaptive boundary control is applied to vibration control of flexible aircraft wing and an autonomous aerial refueling hose system, respectively, and good control results are obtained. In the work by Azimi et al, 13 a sliding mode observer was designed to estimate the uncertainty of ship mechanics and a fractional boundary control method was proposed to suppress the vibration of the riser combined with the backstepping method.…”

“…In recent years, the dynamic analysis and vibration control design of flexible riser systems have made important achievements. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] For the practical marine flexible riser system, there often exist input nonlinearities which include the input deadzone, 22,23 saturation, 2,24,25 backlash, 26,27 hysteresis, 28,29 parameter uncertainty, and so on. These nonlinearities and uncertainty often lead to deterioration of system performance.…”

To suppress the vibration of a flexible riser system with input saturation and uncertain parameters under the influence of unknown external disturbances, an adaptive fuzzy backstepping boundary control algorithm was designed. First, the backstepping method and Lyapunov function are used to analyze the subsystem and design the virtual control law. On this basis, the adaptive fuzzy system was designed to approximate the unknown nonlinear term in the design process, and the smooth hyperbolic tangent function and the auxiliary system based on Nussbaum function were introduced to limit control input. The stability and uniform boundedness of the closed-loop control system are proved by the Lyapunov stability theory without simplifying or discretizing the infinite dimensional dynamic model. Finally, the effectiveness of the proposed control algorithm is verified by comparing the control effect with proportional–integral–derivative control and the previous adaptive backstepping control by MATLAB simulation. The simulation results show that the proposed control algorithm can overcome the uncertainty of system parameters and effectively suppress the riser vibration under input constraints, and its control effect is better than proportional–integral–derivative control and adaptive backstepping control.

“…Although the boundary control of flexible structure has acquired desired results, some of them ignore the problem of input nonlinearities, whereas the nonlinearities caused by physical limitation of system and the actuators cannot be ignored because they are almost impossible to be eliminated, for instance, actuator fault [13,14], hysteresis, saturation, dead zone [15] and backlash [16][17][18][19]. Particularly, input saturation commonly exists in industrial field, and ignoring it will degrade the performance of system and even make system unstable [20].…”

The vibration control of three-dimensional flexible marine riser system with constrained control input is studied in this paper. Combining backstepping method and Lyapunov direct method, an appropriate boundary control which includes smooth hyperbolic tangent function is employed to reduce the vibration of riser system. An auxiliary system which is developed based on Nussbaum function is proposed to tackle with nonlinear constrained input. The closed-loop system is stable ultimately, and the displacement of riser is uniformly bounded which can be proven by Lyapunov synthesis without any discretization or simplification of the dynamic in the time and space. Moreover, the effectiveness of proposed boundary control is illustrated by comparing with SMC (sliding mode control) in the simulation part. The simulation results show that the proposed control can achieve better control performance with a constrained input.

“…In this context, one of the major goals in the design of aerospace structures is to increase the efficiency of their dynamic responses to enhance their fatigue characteristics as well as their fluidstructure interaction stabilities. A wide range of vibration control devices have been proposed in the literature, characterized by passive, adaptive, semi-active [13,14] or active nature [15,16], and can be effectively implemented to achieve those design requirements. Of particular interest are the passive vibration attenuation devices.…”

This thesis proposes an optimization procedure to achieve the best configuration of Multiple Degrees of Freedom (MDOF) tuned mass dampers (TMD) to mitigate the global dynamic aeroelastic response of aerospace structures. The TMD design parameters are investigated in terms of their individual mass, stiffness, damping, and location on the target structure. In order to determine the optimum sets of TMD, a Multi-Objective design optimization employing Genetic Algorithm (MOGA) is implemented, where the selected fitness functions for the analysis are the minimization of the total mass included with the resonators and concurrent minimization of the peak displacement at a specific structural nodes in space.Two case studies are presented where the method proposed is tested to minimize the pointing error of large Earth-based radio antenna structures. Fourteen different operational scenarios of wind gust are considered employing two models of atmospheric disturbances, namely, the Power Spectral Density (PSD) represented by the Davenport spectrum (DS), and the Tuned Discrete Gust (TDG) where the dynamic aeroelastic response of the structure is analyzed in the frequency and the time domains, respectively.In the first case study, the inclusion of multiple-TMD in the antenna structure is analyzed and compared with different placement configurations of the multiple-TMD devices. Here, the performance of the antenna structure in the form of its pointing error and the corresponding multiple-TMD inclusion are discussed at length. It is found that the placement of the multiple-TMD in the primary reflector of the antenna provides a maximum reduction in the pointing error of the antenna of 62.0% and 39.2% while subject to PSD and TDG gust disturbances , respectively. iv In the second case study, a single-TMD configuration is investigated to concurrently attenuate the aeroelastic response of all 14 operational cases considering the frequency and time-domain gust models. It is found that the optimal solutions are capable of reducing the structural response by an average of 66% and 50% for the PSD and TDG gust excitation scenarios, respectively, with a mass inclusion of 1% of the total mass of the antenna structural.Finally, this study proposes an advanced framework to estimate the optimal parameters of TMD attenuation devices, under complex loadings conditions, as an initial step in the direction of the use of such passive systems in applications that commonly employ active or semi-active attenuation solutions.
