Design and Analysis of a Small-Scale Wind Energy Conversion System
… prototype to be used for testing different control strategies applied to small scale WECSs. Novel control algorithms will be proposed to the WECS and will be verified experimentally in details. The wind turbine aerodynamics are presented and mathematical modeling is derived which is used …

Axial Compressor Design with Counter-Rotation and Variable RPM for Stall Mitigation
<p>Compressor Stall, an aerodynamic instability due to abnormal air flow in the compressor resulting in loss of total pressure and compressor performance. One of the reasons of compressor stall is due to rise in static back pressure at compressor exit which may result from an imbalance of incidence …

The Dynamics of Stall and Surge Behavior in Axial-Centrifugal Compressors
The phenomena of stall and surge in axial-centrifugal compressors is investigated through high-response measurements of both the pressure field and the flowfield throughout the surge cycle. A unique high-response forward-facing and aft-facing probe provides flow information. Several …

L1 Adaptive Control of Uncertain Nonlinear Systems with Dynamic Constraints: As Applied to Commercial Aircraft Engines
<p>L1 adaptive control for a turbofan commercial aircraft engine is developed and applied in the presences of constraint limits. Turbofan engines are a highly complex system, with a wide variety of dynamics, operating under constantly changing environmental conditions. In aircraft turbofan …

Unsteady separation control on wind turbine blades
Dynamic stall is one of the primary causes of unsteady loads on wind turbine blades. The process can be instigated by a multitude of factors, common in wind turbine operating environments, such as inflow turbulence, wind gusts and sustained yaw misalignment. The unsteady separation due to dynamic …
