Summary: This paper introduces a method to control the vertical vibration of a mobile manipulator by designing a vibration damping control method of a simplified double inverted pendulum model. The method uses static output feedback with min-max control to achieve desired closed-loop stability and effectively suppress disturbance, even in the presence of system uncertainty. The effectiveness of the proposed control method is demonstrated through simulations comparing with LQR control.

Summary: In this paper, we investigate the problem of vibration suppression and boundary control for a nonlinear flexible rotating manipulator in three-dimensional space. We propose a boundary control approach based on partial differential equations model to suppress distributed elastic deformation and vibration and ensure the desired angle of the base and link. The Barrier Lyapunov function is used to keep the output signal within a safe and adjustable range. Finally, digital simulation is performed to validate the effectiveness of the designed control strategy.

Summary: This paper discusses a contact-force control and vibration suppression problem for a constrained one-link flexible manipulator with unknown control direction and time-varying actuator fault. The manipulator is described by a Partial Differential Equation model. The Nussbaum function is used to solve the unknown control direction and time-varying actuator fault problems and construct an adaptive boundary controller to control the contact force and eliminate the vibration of the flexible manipulator. The Variable Separation Technique is used to prove the necessary existence and uniqueness of the system solution more concisely.

Summary: Expanding the functions of submarines by carrying underwater manipulators with a large working space is of great importance. To suppress the flexible vibration of underwater manipulators, an improved sparrow search algorithm (ISSA) combining an elite strategy and a sine algorithm is proposed. Simulation results show that ISSA algorithm outperforms other algorithms in terms of optimization performance. However, due to the complexity of the dynamics model, ISSA is difficult to apply directly in practice.

Summary: In this study, a motion-based control (MBC) method with designed motion profiles is introduced to reduce the endpoint vibrations of epoxy-glass-reinforced composite manipulators. The effectiveness of MBC is evaluated by comparing the change in RMS values of endpoint vibration responses and the reduction rates for all motion profiles. The results show significant advantages for the MBC method, reducing vibrations by approximately 99% and eliminating positioning errors caused by vibrations.

Summary: The piezoelectric energy harvesting performances of smart wind blades and smart drone propellers using lead zirconate titanate (PZT) material were evaluated. The energy harvesting performance of the smart wind blades was influenced by the blade angles, while the performance of the smart drone propellers depended on the sensor responses and polarization directions. The maximum and minimum power outputs obtained were approximately 0.086 W and 0.008 W, respectively. The results indicated that the z-polarized smart propeller had better energy harvesting performance than the y polarization, and the amount of energy obtained increased with the rotation speed and endpoint vibration amplitudes.
