Investigating Negative Capacitance Shunt Circuit for Broadband Vibration Damping and Utilizing ACO for Optimization

Abstract: This paper presents optimization of vibration damping for a rectangular thin plate using a single piezoelectric (PZT) patch shunted with negative capacitance, by utilizing the ant colony optimization (ACO) algorithm. The frequency range to be controlled is presented in the context of statistical energy analysis (SEA) where modal overlap factor (MOF) is considered i.e. MOF
