NASA SBIR Phase II: Bifurcation Analysis and Nonlinear Control

Feb. 2005: NASA Langley has awarded a Phase II SBIR contract to develop bifurcation analysis for aircraft. The development of relevant analytical and simulation-based technologies for the prediction and control for fail-safe adaptivity under adverse and upset conditions is an important step in advancing flight safety goals. Impaired aircraft operate much closer to bifurcation points than a fully functional vehicle. Thus, it is necessary to be able to evaluate aircraft and flight control system performance near stability boundaries. Understanding behavior near operational limits and developing control and recovery strategies for these circumstances is fundamental to achieving that goal. Dr. Gaurav Bajpai will be the principal investigator on the effort.
