Interdisciplinary Basic Research in Smart Materials & Structures
Abstract
Key contributions include the following: (1) The adaptation and specialization of multi-channel vibration control techniques based on the characteristic vibration disturbance; (2) Demonstrated the importance of using combinations of multi-channel controller formulations for transient and steady-state vibration disturbance suppression and rejection; (3) Developed a new Hybrid Active Control Formulation which incorporates combination of a Nonlinear-rate feedback scheme and the Filtered-x adaptive feedforward controller for transient and steady-state disturbance suppression and rejection; (4) Developed a novel model-independent Total Energy Absorption (TEA) active control scheme for active vibration control in structures with vibration response characterized by standing and propagating waveforms. (5) Developed a new Dual Active Control Scheme which incorporates a fuzzy adaptive leaning rate with the Filtered-x algorithm for separate/combined vibration and acoustic radiation reduction.
