Disturbance Accommodating Adaptive Control with Application to Wind Turbines
Dr. Susan Frost, Intelligent Systems Division, NASA Ames Research Center
Date: Wednesday, December 5th, 2012, 6:45-8:00pm

Abstract: Adaptive control techniques are well suited to applications that have unknown modeling parameters and poorly known operating conditions. Many physical systems experience external disturbances that are persistent or continually recurring. Flexible structures and systems with compliance between components often form a class of systems that fail to meet standard requirements for adaptive control. For these classes of systems, a residual mode filter can restore the ability of the adaptive controller to perform in a stable manner. New theory will be presented that enables adaptive control with accommodation of persistent disturbances using residual mode filters. After a short introduction to some of the control challenges of large utility-scale wind turbines, this theory will be applied to a high-fidelity simulation of a wind turbine.
Dr. Frost is a research engineer with NASA Ames Research Center working on control problems for aircraft and wind turbines. She has the following degrees: PhD, MS Electrical Engineering, and MS Mathematics from the University of Wyoming and BA Mathematics from Wellesley College.
Directions: Exit 101 on Moffett Blvd Exit and proceed to the Security Gate. You will pass through the security gate to reach the campus. A valid driver’s license, state ID, or federal ID is required. When presenting your ID, let them know you are going to Carnegie Mellon.
After Passing Through the Security Gate: Once you proceed through security gate, move into the right lane before you approach the “Y” in the road (about 200 yards from the security gate). Continue in the right lane as the road bends right, a chapel will be on your right. Carnegie Mellon’s Building 23 is directly to your left. Make an immediate left into the Building 23 parking lot. You are now in the back of Building 23. Follow the signs/lights to the main entrance in the front of the building.
The meeting will start with food and beverages at 6:45 PM with the talk starting at 7:00PM.
