AbstractIn many structures with vibration problems, the nature of the problem is uncertain, or varies over time. Thus it is not possible 'a priori to design a linear, time-invariant, (LTI) feedback control law which is guaranteed to meet performance, or possibly even stability requirements over the entire operating range. These applications require an intelligent control system which can adapt to the changes in its environment.ACX proposes to develop an adaptive, compact, integrated SmartPack for vibration reduction in systems with time-varying harmonic disturbances or uncertain time-invariant dynamics. Each package would include actuators and sensors, drive and signal conditioning electronics as well as complex, intelligent controllers to yield a self-standing solution to a wide range of vibration problems. The packaging will provide a protective skin offering electrical isolation, and a means for integration of sensors, signal conditioning and control electronics. The ability of the adaptive SmartPack to reduce vibration levels or perform structural control tasks in a time-varying disturbance environment will be evaluated during testing and characterization. The Phase II effort would refine the design of the device, produce a manufacturing plan for high volume production, and isolate a target commercial application.
