Title: Digital control of smart structures

Abstract: Modular control patches including assemblies of sensors and actuators are provided to impart or control vibration of foundation members such as struts in aerospace apparatus. Local digital electronic control means is associated with each control patch assembly. Programmable digital compensators in the control permits operation of the patches to be remotely varied. Patches are attached mechanically or by chemical bonding to the outside of the struts so that the electronics can be selectively removed and replaced. The patch being the sensors and actuators may also be attached or embedded with a composite structure.
