Nonlinear Controller For Nonlinear Wave Energy Converters, David G. Wilson, Giorgio Bacelli, Rush D. Robinett Iii, Ossama Abdelkhalik

Michigan Tech Patents

The present invention is directed to a nonlinear controller for nonlinear wave energy converters (WECs). As an example of the invention, a nonlinear dynamic model is developed for a geometrically right-circular cylinder WEC design for the heave-only motion, or a single degree-of-freedom (DOF). The linear stiffness term is replaced by a nonlinear cubic hardening spring term to demonstrate the performance of a nonlinear WEC as compared to an optimized linear WEC. By exploiting the nonlinear physics in the nonlinear controller, equivalent power and energy capture, as well as simplified operational performance is observed for the nonlinear cubic hardening spring controller …

Multi-Resonant Feedback Control Of Multiple Degree-Of-Freedom Wave Energy Converters, Ossama Abdelkhalik, Shangyan Zou, Rush D. Robinett Iii, David G. Wilson, Giorgio Bacelli, Ryan G. Coe, Umesh Korde

Michigan Tech Patents

Multi-resonant control of a 3 degree-of-freedom (heave-pitch-surge) wave energy converter enables energy capture that can be in the order of three times the energy capture of a heave-only wave energy converter. The invention uses a time domain feedback control strategy that is optimal based on the criteria of complex conjugate control. The multi-resonant control can also be used to shift the harvested energy from one of the coupled modes to another, enabling the elimination of one of the actuators otherwise required in a 3 degree-of-freedom wave energy converter. This feedback control strategy does not require wave prediction; it only requires …

Multi-Resonant Feedback Control Of A Single Degree-Of-Freedom Wave Energy Converter, David G. Wilson, Rush D. Robinett Iii, Ossama Abdelkhalik, Jiajun Song, Giorgio Bacelli

Michigan Tech Patents

A multi-resonant wide band controller decomposes the wave energy converter control problem into sub-problems; an independent single-frequency controller is used for each sub-problem. Thus, each sub-problem controller can be optimized independently. The feedback control enables actual time-domain realization of multi-frequency complex conjugate control. The feedback strategy requires only measurements of the buoy position and velocity. No knowledge of excitation force, wave measurements, nor wave prediction is needed. As an example, the feedback signal processing can be carried out using Fast Fourier Transform with Hanning windows and optimization of amplitudes and phases. Given that the output signal is decomposed into individual …

Model Predictive Control Of Parametric Excited Pitch-Surge Modes In Wave Energy Converters, Ossama Abdelkhalik, Rush D. Robinett Iii, Shangyan Zou, David G. Wilson, Giorgio Bacelli, Umesh Korde, Ryan G. Coe

Michigan Tech Patents

A parametric excitation dynamic model is used for a three degrees-of-freedom (3-DOF) wave energy converter. Since the heave motion is uncoupled from the pitch and surge modes, the pitch-surge equations of motion can be treated as a linear time varying system, or a linear system with parametric excitation. In such case the parametric exciting frequency can be tuned to twice the natural frequency of the system for higher energy harvesting. A parametric excited 3-DOF wave energy converter can harvest more power, for both regular and irregular waves, compared to the linear 3-DOF. For example, in a Bretschneider wave, the harvested …

Printing 3d Models For Chemistry: A Step-By-Step Open-Source Guide For Hobbyists, Corporate Professionals, And Educators And Students In K-12 And Higher Education, Elisabeth Grace Billman-Benveniste, Jacob Franz, Loredana Valenzano-Slough

Open Access Books

3D-printing is a relatively inexpensive additive manufacturing method used to create tangible objects. As a relatively new technology, the true capability of 3D-printing has not yet been fully exploited, especially in academic and research/teaching settings. Through this work, 3D-printing in a classroom and research environment is employed as a tool for creation of fully customizable, three-dimensional molecular models and for the visualization of theoretical abstract concepts.

Electro-Optic Modulator, Microwave Photonic Link Including An Electro-Optic Modulator, And Method Of Communicating A Signal With An Electro-Optic Modulator, Christopher T. Middlebrook, Arash Hosseinzadeh

Michigan Tech Patents

An electro-optic modulator coupled to an optical source providing an optical power and a radio frequency source providing a radio frequency power. The electro-optic modulator includes a waveguide to receive the optical power, a first ring resonator modulator, and a second ring resonator modulator. The first ring resonator modulator and the second ring resonator modulator receives the radio frequency power, and are coupled to the waveguide for modulating the optical power with the radio frequency power. The first ring resonator modulator and the second ring resonator modulator, with the waveguide, substantially suppress third order intermodulation distortion of a combined power. …

Pseudo-Spectral Method To Control Three-Degree-Of-Freedom Wave Energy Converters, Ossama Abdelkhalik, Giorgio Bacelli, Shangyan Zou, Rush D. Robinett Iii, David G. Wilson, Ryan G. Coe

Michigan Tech Patents

The invention provides optimal control of a three-degree-of-freedom wave energy converter using a pseudo-spectral control method. The three modes are the heave, pitch and surge. A dynamic model is characterized by a coupling between the pitch and surge modes, while the heave is decoupled. The heave, however, excites the pitch motion through nonlinear parametric excitation in the pitch mode. The invention can use a Fourier series as basis functions to approximate the states and the control. For the parametric excited case, a sequential quadratic programming approach can be implemented to numerically solve for the optimal control. The numerical results show …

The magnet is positioned a second distance from the emitter, and the emitter is positioned between the extraction electrode and the magnet. The …

Agent-Based Microgrid Architecture For Generation Following Protocols, Steven Goldsmith

Michigan Tech Patents

A system for predicting power and loads over a single, relatively short time horizon. More specifically, a system comprising a Storage Agent (S-agent) Cohort within a grid control society, wherein the system expands G and L intra-cohort protocols to allow the S-cohort to participate in power management of the grid by scheduling storage components in source or load roles as determined by the time-varying state of the power imbalance and by the risk-adjusting capacity margin relationship between the G and L cohorts.

Optimal Control Of Wave Energy Converters, Ossama Abdelkhalik, Rush D. Robinett Iii, Shangyan Zou, Giorgio Bacelli, David G. Wilson, Umesh Korde

Michigan Tech Patents

A wave energy converter and method for extracting energy from water waves maximizes the energy extraction per cycle by estimating an excitation force of heave wave motion on the buoy, computing a control force from the estimated excitation force using a dynamic model, and applying the computed control force to the buoy to extract energy from the heave wave motion. Analysis and numerical simulations demonstrate that the optimal control of a heave wave energy converter is, in general, in the form of a bang-singular-bang control; in which the optimal control at a given time can be either in the singular …

Method To Provide Meta-Stable Operation Of Dc Microgrid Comprising A Pulsed Load, David G. Wilson, Wayne Weaver, Rush D. Robinett Iii, Ronald Matthews, Steven F. Glover

Michigan Tech Patents

A Hamiltonian surface shaping power flow control (HSSPFC) method is used to analyze the meta-stability and adjust pulsed power loads on a DC electric power distribution network. Pulsed power loads are nonlinear, time-variant systems that cause nonlinear limit-cycles. During the on periods of a pulsed load, the system can be in an unstable state and is damped back to stability during the off state of the load. Therefore, over the entire period of the pulse the system may only be assessed as meta-stable. As shown through simulation, HIL and hardware results, the HSSPFC method is more accurate than the other …
