Optimization of partial-state feedback for vibratory energy harvesters subjected to broadband stochastic disturbances

Abstract

In many applications of vibratory energy harvesting, the external disturbance is most appropriately modeled as a broadband stochastic process. Optimization of the average power generated from such disturbances is a feedback control problem, and solvable via LQG (linear–quadratic–Gaussian) control theory. Implementing the optimal feedback controller requires… (More)
