In this paper, angle tracking and vibration suppression of a 3D flexible rotatable manipulator system considering uncertain actuator dynamics unknown end payload are investigated. The is characterised using partial differential equation model established through the Hamilton principle. An adaptive control law, grounded in Nussbaum function, developed to address challenges stemming from dynamics. Additionally, issue payload, projection mapping operator used devise an law. Theoretical analysis...
This paper proposes an adaptive fault-tolerant control scheme for a single-link flexible manipulator with actuator failure and uncertain boundary disturbance. The dynamic model of the as-described by partial differential equations (PDEs) is derived under Hamilton’s principle. then used to design (FTC) which tracks given angle regulates vibration in case failure. disturbance compensated radial basis function (RBF) neural network. whole closed-loop system proven asymptotically stable Lyapunov...
Summary This study investigates the event‐triggered adaptive control issues of a flexible manipulator when system is implemented over network. The has two actuators, which receive signals from controller through communication Given limited problem network and potential actuator failures, an fault‐tolerant proposed based on partial differential equation model. In our design, event‐triggering mechanisms are introduced to avoid continuous signal transmission actuator. Then, law using projection...
This paper proposes an active adaptive fault-tolerant control scheme for position tracking and vibration suppression of a constrained moving rigid-flexible manipulator system (RFMS) in three-dimensional (3D) space. The investigated RFMS comprises four parts: vehicle, rotatable base, rigid link, flexible which is first modeled using nonlinear partial differential equations (PDEs) terms Hamilton’s principle. may suffer from unknown actuator faults, the proposed strategy can compensate faults...
In this study, we evaluate the coordination tracking control problem of a flexible master–slave teleoperation system.

With recent advancements in the development of material and manufacturing technology, leading edge geometry turbomachine blades has attracted widespread attention. “Sharp” edges always have a better aerodynamic performance, though it is prone to deformations easily. Thus, flat plates real compressor cascades with different were investigated study influence, which applicable for thin at low speeds. Different boundary layer characteristics, including velocity profile, transition process, loss,...
Speckle reduction is a key preprocessing approach for the applications of Synthetic Aperture Radar (SAR) data. For many interpretation tasks, high-quality SAR images with rich texture and structure information are useful. Therefore, satisfactory image filter should retain this well after processing. Some quantitative assessment indicators have been presented to evaluate edge-preservation capability single-polarization filters, among which non-clean-reference-based (i.e., blind) ones...
In this paper, the current distribution and an input impedance of a horizontal linear antenna in presence layered region are investigated both analytically numerically. particular, we demonstrate case four-layered region. The wave-number characteristic eccentrically insulated obtained first. Subsequently, analytical formula for on is derived by applying limiting process. computational results show that upper lower dielectric layers have different effects antenna. It also found imaginary part...
Most icing studies use 2D or quasi-3D models, ignoring the effects of blade span and tip icing. In this paper, a new model for predicting 3D vertical axis wind turbine blades by supplementing is established, characteristics under multiple working conditions are simulated step from time scale, unsteady laws compared analyzed. Ice properties surface temperature distribution determine corresponding deicing power. The analysis results show that unfrozen water film flows in spanwise direction...
