Ohio State (OSU) and Stanford Universities are cooperating to understand quadruped galloping through the design of a self-contained, biomimetic, galloping robot. The leg for this quadruped was first designed at Ohio State University (OSU). A second-generation leg, with the same functional geometry, has been designed and tested at Stanford University. The objective of these tests was to determin...

Introduction: Efficient gait control using Functional Electrical Stimulation (FES) is an open research problem. In this research, a new intermittent controller has been designed to control the human shank movement dynamics during gait. Methods: In this approach, first, the three-dimensional phase space was constructed using the human shank movement data recorded from the healthy subjects. Then...

3D Virtual Environments (VE) are becoming popular as a tool for cognitive, functional and psychological assessment. Navigation in these environments is recognized as one of the most difficult activities in 3D Virtual Environments (VE). Users unfamiliar to 3D games, specially elder persons, get puzzled when they try to virtually move an avatar through these environments. Their inability to navig...

The aim of this research work is to modulate the pitch angle both types wind turbines based on fuzzy logic control (FLC), as changes in have various functions horizontal and vertical axis turbines. For HAWT, applied shield electrical components turbine when speed exceeds rated without shutting down turbine. FLC used angular velocity using two inputs one output with three membership for output. ...

An Adaptive Augmenting Control (AAC) algorithm for the Space Launch System (SLS) has been developed at the Marshall Space Flight Center (MSFC) as part of the launch vehicle’s baseline flight control system. A prototype version of the SLS flight control software was hosted on a piloted aircraft at the Armstrong Flight Research Center to demonstrate the adaptive controller on a full-scale realist...

Extraction of maximum energy from wind and transferring it to the grid with high efficiency are challenging problems. To this end, this study proposes a smart pitch controller for a wind turbine-doubly fed induction generator system using a Differential Evolution (DE) based adaptive neural network. The nominal weights for the back-propagation neural network controller are obtained from input-ou...

Floating offshore wind turbines (FOWTs) are systems with complex and highly nonlinear dynamics; they subjected to heavy loads, making control classical strategies a challenge. In addition, experience vibrations due waves. Furthermore, the of blade angle itself may generate vibrations. To address this issue, in work we propose design an intelligent system based on fuzzy logic maintain rated powe...
