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 ...

Concentric Contra-Rotating Dual Shaft Vertical Axis Wind Turbine, Emily Walz, Marcellin Zahui, Andrew Shires, Carl Gilkeson

Essential Studies UNDergraduate Showcase

A typical vertical axis wind turbine (VAWT) consists of two or more airfoils all attached to a single central axis. The wind turbine style most commonly found in renewable energy is the horizontal axis wind turbine (HAWT) that have a high energy production efficiency in exchange for requiring large amounts of land and air space. Alternatively, a VAWT can function in low speeds and in smaller less typical locations. As a result, novel VAWT designs are researched to improve their energy efficiency. An example of a novel VAWT is the concentric counter-rotating VAWT investigated theoretically using the 2D computational fluid ...

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 ...

Automated Din Rail Cut And Punch Machine, Youssif Alkheder, Gaston Charreun, Derrian Flemings, Jonathan Liss

Capstone Design Expo Posters

Our project’s main goal is to optimize the process of punching and cutting DIN rail in a manufacturing setting. The current method for cutting and punching DIN rails is tedious and simply too time consuming. An operator is needed to manually load the DIN rail into the cutter, measure the required length and activate the cutter. While this simple process may not take too long at first glance, companies, like Weidmuller, must be able to produce large-quantity orders to successfully meet the demands of their customers. By turning to automation, we are effectively reducing the amount of time it ...
