Large amplitude vibrations are often associated with geometric nonlinearity. These nonlinear systems usually controlled using linear controllers, such as positive position feedback (PPF). Nonlinear control has also been limited to single-input single-output (SISO) architectures. The present study develops a PPF controller implemented both SISO and multiple-input multiple-output (MIMO) architecture on real experimental set-up, consisting of clamped composite sandwich beam. aimed reduce the...
PPF (Positive Position Feedback) is a highly effective algorithm for controlling mechanical vibrations in thin-walled structures.It easy to use with piezoelectric patches and has useful modal characteristics.However, when using MIMO (Multi-Input Multi-Output) architecture, it necessary convert physical signals from transducers into coordinates, which done by placing participation matrices between sensors, controllers, actuators.These can be difficult determine, especially the number of...
Abstract Active Vibration Control (AVC) of electromechanical systems has been an active field research for decades. One main challenge in AVC techniques is the design control laws. In most cases, entirely based on numerical models, thus making high-fidelity models greatly desirable. However, analytical or finite element are intrinsically onerous and rarely consider imperfections real-life structures. To overcome this drawback, work presents a method to obtain model built upon collection set...
Abstract Multiple input multiple output active vibration control architectures pose some common challenges to designers, such as the optimization of number and position sensors actuators, controller parameters. At a more fundamental level, however, modeling electromechanical structure under is preliminary step necessary perform all optimizations described above. While algorithms try prescind from detailed modeling, models are always required simulate numerically performance control. Finite...
