“…The resulted show that the vibrations induced by complex multi-frequency excitation with different amplitudes were effectively reduced with MFC piezoelectric patches. Wang et al [23] investigated vibration suppression for a high-speed macro-micro manipulator with structural flexibility and parameter perturbation. In the study, the macro-micro manipulator contained an air-floating macro-motion platform and an MFC micromanipulator.…”

In order to improve the vibration suppression effect of the flexible beam system, active control based on soft piezoelectric macro-fiber composites (MFCs) consisting of polyimide (PI) sheet and lead zirconate titanate (PZT) is used to reduce the vibration. The vibration control system is composed of a flexible beam, a sensing piezoelectric MFC plate, and an actuated piezoelectric MFC plate. The dynamic coupling model of the flexible beam system is established according to the theory of structural mechanics and the piezoelectric stress equation. A linear quadratic optimal controller (LQR) is designed based on the optimal control theory. An optimization method, designed based on a differential evolution algorithm, is utilized for the selection of weighted matrix Q. Additionally, according to theoretical research, an experimental platform is built, and vibration active control experiments are carried out on piezoelectric flexible beams under conditions of instantaneous disturbance and continuous disturbance. The results show that the vibration of flexible beams is effectively suppressed under different disturbances. The amplitudes of the piezoelectric flexible beams are reduced by 94.4% and 65.4% under the conditions of instantaneous and continuous disturbances with LQR control.

Perturbation in a system is one of the troublesome matters in dynamics, vibration, and control. It changes the system's behavior and possibly causes a mechanical failure. This paper presents the effect of perturbations on the decay curve of a damped vibration system. The perturbations are varied from single to multiple forces to give novel knowledge completing previous studies. Additionally, the system properties, i.e., damping and stiffness, are also varied to provide more meaningful comprehensive information and, thus, can be used in further vibrational system developments. The result shows that the multiplication of perturbation force significantly changes the decay curve slope with unique characteristics. The variation of damping and stiffness also affects the vibration amplitude and the system resonance.

“…They also presented a hybrid control strategy consisting of a trajectory planning method of the joint angle of the macro stage and an adaptive variable structure control by the MFC actuator to simultaneously suppress the vibration during and after the positioning. Wang et al [14] proposed a robust vibration control technique for the MFC micromanipulator based on a macro stage in translational motion. They employed an asymmetric Prandtl-Ishlinskii hysteresis model in their proposed technique to capture the hysteresis nonlinearity of an MFC.…”

In this paper, we examine a point-to-point motion task of a flexible manipulator with macro fiber composite (MFC) and then propose a new feedforward control method to suppress driving energy and residual vibration simultaneously. For this, we use an MFC attached to one side of the flexible manipulator that has one revolute joint as an actuator. We attempt to express the joint angle in the control technique by combining cycloidal and polynomial functions. On the other hand, the input voltage profile of the MFC is expressed using Gaussian functions. The trajectory of the joint angle and the input voltage profile are dependent upon the coefficients of the polynomial function and the Gaussian functions, respectively. The trajectory and the input voltage profile are optimized simultaneously to cancel the residual vibration under saving energy by tuning the coefficients using the particle swarm optimization algorithm. The effectiveness of the proposed method is verified by performing simulations and experiments. Thus, our findings confirmed that the simultaneous optimization of the trajectory of the joint angle and the input voltage of the MFC saves more energy than only the optimization of the trajectory. Therefore, we could establish an energy-saving feedforward control method by driving two actuators.
