Patent number: 7216018Abstract: A controller f or multi-DOF active vibration isolation accounts for plant uncertainties and payload disturbances using dynamic frequency-shaped sliding control. Modal decomposition rewrites a multi-DOF vibration control problem as a combination of modal problems. Modal parameters can be extracted. Target frequency-domain performance, e.g., a skyhook, is recast as a frequency-shaped sliding surface. Boundary layer approximation is examined. Skyhook can be robustly achieved. The manifold is also extends to adaptive vibration isolation without model reference. Nonlinear target dynamics of the same order as the plant can be attained. Control can be achieved without measuring excitation or knowing mass, stiffness and damping matrices. Control for plants subject to disturbances other than vibration can be achieved for any that can be described by equations the same character as those that describe mechanical dynamic systems. The target dynamics can be any, even non-linear.Type: GrantFiled: June 28, 2004Date of Patent: May 8, 2007Assignee: Massachusetts Institute of TechnologyInventors: Lei Zuo, Jean-Jacques E. Slotine

Publication number: 20050256613Abstract: A robust controller for multi-degree-of-freedom active vibration isolation accounts for plant uncertainties and payload disturbances using frequency-shaped sliding control. Modal decomposition is used to rewrite a multi-degree of freedom vibration control problem as a combination of individual modal control problems in modal coordinates. Modal parameters for decomposition and modelling can be extracted from theoretical or experimental modal analysis. The target frequency-domain performance of isolation, for example a skyhook model, is recast as a frequency-shaped sliding surface. Boundary layer approximation is examined. The ideal skyhook effect can be robustly achieved. The frequency-shaped manifold is also extended to adaptive vibration isolation without model reference, which has been verified by experiments, and demonstrated to be very effective for vibration isolation. Nonlinear target dynamics of the same order as the nominal plant can also be attained.Type: ApplicationFiled: June 28, 2004Publication date: November 17, 2005Applicant: Massachusetts Institute of TechnologyInventors: Lei Zuo, Jean-Jacques Slotine
