Abstract
This study presents a hybrid modeling and control approach based on the integration of ANSYS and MATLAB for the active vibration control of flexible space structures. The structural dynamics were obtained through high-degree-of-freedom models via ANSYS APDL and transformed into a reduced-order state-space model (ROSSM) representing the rigid-flexible interaction for controller design. Performance analyses of the designed Pole Placement (PP) controller revealed that a damping ratio of 0.70 rapidly stabilizes oscillations under shock inputs; however, it was observed that this high damping performance significantly increases the control force requirements on the actuator. Sensitivity analyses conducted in the final stage of the study confirmed that the controller maintains its stability despite 10% variations in material properties, demonstrating a robust performance against parametric uncertainties.
This study presents the dynamic modeling and control of a clamped-free beam system using Proportional–Integral–Derivative (PID) control strategies, with a focus on comparing the performance of a Standard PID controller and an optimally Tuned PID controller. Flexible beam structures are widely used in robotic and precis...

Flexible satellite structures with lightweight solar panels are naturally prone to structural vibrations caused by attitude maneuvers, continuous environmental disturbances and deformation during deployment. These vibrations can lead to a decrease in pointing accuracy, a degradation in payload performance, and an adver...

This study addresses the inherently low damping and vibration susceptibility of carbon fiber reinforced polymer (CFRP) laminated cantilever plates by developing a comprehensive dynamic modeling and active vibration control framework. An electromechanical coupling model incorporating macro-fiber composite (MFC) actuator...
The limited availability of energy resources in space implementations requires the use of low-power and low-capacity actuators in satellite manipulators. This constraint makes it necessary to employ the manipulator structure to be lightweight in order to maintain task performance; however, the resulting increase in str...

This paper presents a passivity-based sliding-mode controller-observer for a two-link lightweight robotic arm that accounts for structural flexibility and payload mass. The system’s dynamical model is obtained using the Euler-Lagrange formalism and the assumed modes method. The resulting mathematical model is highly no...

Cable-driven manipulators have garnered increasing attention in robotics owing to their lightweight structure, flexible transmission mechanisms, and large operational workspace. However, the strong nonlinear dynamics, parameter coupling, and external disturbances inherent in cable-driven systems pose significant challe...
