    Abstract

    The paper presents real-time life extending control of complex mechanical structures based on the anomaly information generated via symbolic time series analysis. The underlying concept is experimentally validated on a multi-degree of freedom mass-beam structure excited by oscillatory motion of two shakers. The control policy is formulated based on the analysis of stochastic time series data of ultrasonic sensors collected under identical loading conditions. Experimental results demonstrate feasibility of the real-time control strategy for fatigue life extension of polycrystalline alloy structures.
