Electromechanical impedance based self-diagnosis of piezoelectric smart structure using principal component analysis and LibSVM
Abstract The long-term use of a piezoelectric smart structure make it difficult to judge whether the structure or piezoelectric lead zirconate titanate (PZT) is damaged when the signal changes. If the sensor fault occurs, the cases and degrees of the fault are unknown based on the electromechanical...
