Paper Abstract

In this paper, we propose a new method for tuning parameters in a negative capacitor circuit, which is utilized in the piezoelectric shunt damping. A stochastic numerical optimization method, called Covariance Matrix Adaptation-Evolution Strategy (CMA-ES), is selected to minimize the effect of disturbance to an experimental setup. In addition, an additional restriction is imposed on CMA-ES so that the internal stability of the closed-loop system is guaranteed. The effectiveness of the proposed method is demonstrated by numerical examples.
