Large-Scale Self-Powered Vibration Control: Theory and Experiment
Connor Ligeikis, Heath Hofmann, Jeff Scruggs
A self-powered system is a control technology that powers itself by harvesting energy from exogenous disturbances. This article details the design and experimental validation of a…
Causal, Stochastic MPC for Wave Energy Converters
Connor H. Ligeikis, Jeffrey T. Scruggs
We implement a causal model predictive control (MPC) strategy to maximize power generation from a wave energy converter (WEC) system, for which the power take-off (PTO) systems hav…
Multi-Objective Vector Control of a Three-Phase Vibratory Energy Harvester
Connor H. Ligeikis, Jeffrey T. Scruggs
In vibration energy harvesting technologies, feedback control is required to maximize the average power generated from stochastic disturbances. In large-scale applications it is of…
On the Feasibility of Self-Powered Linear Feedback Control
Connor H. Ligeikis, Jeffrey T. Scruggs
A control system is called self-powered if the only energy it requires for operation is that which it absorbs from the plant. For a linear feedback law to be feasible for a self-po…
