Active Vibration Control of Membrane Structures

Membrane structures—thin, flexible surfaces held in tension—are prized for their low weight, ease of deployment and adaptability across civil, aerospace and optical applications. Their lack of bending stiffness and pronounced geometric nonlinearity, however, make them highly susceptible to dynamic disturbances ranging from wind buffeting and hail impact to thermal and inertial loads. Active vibration control addresses these challenges by integrating sensors and actuators—often piezoelectric or electroactive materials—within a closed-loop framework that monitors vibration and applies corrective inputs in real time. Control strategies span classical proportional–integral–derivative schemes to advanced adaptive, robust and optimal algorithms. Recent advances have yielded precise modal damping, shape regulation of membrane mirrors to micron-level accuracy and suppression of rigid–flexible coupling effects in space-borne antennas. The global significance of this work lies in extending service life, improving performance and ensuring the operational integrity of lightweight membrane systems in demanding environments.

Adaptive Shape Control for Thermal Deformation of Membrane Mirror with In-plane PVDF Actuators introduced a closed-loop system in which polyvinylidene fluoride patches serve as both sensors and actuators. By constructing an influence-function matrix, authors achieved rapid, real-time shape adjustments of a polyimide membrane mirror, reducing surface deviations from 20 μm to submicron levels within 0.1 s. Nonlinear Dynamics of a Space Tensioned Membrane Antenna during Orbital Maneuvering developed a coupled rigid–flexible model capturing how spacecraft rotations alter membrane stiffness and damping. Numerical solutions demonstrated that manoeuvre-induced accelerations directly influence vibration frequency and amplitude, guiding actuator placement and control law design for intelligent vibration suppression. Thermal Analysis and Rigid-Flexible Coupling Dynamics of a Satellite with Membrane Antenna combined finite-element thermal modelling with hybrid-coordinate dynamic equations to characterise temperature-dependent modal shifts. A component synthesis vibration suppression controller was shown to mitigate attitude-maneuver-induced oscillations effectively, improving pointing accuracy in thermally challenging orbital environments.
