Nonlinear stability and control study of highly maneuverable high performance aircraft, phase 2

摘要: This project is intended to research and develop new nonlinear methodologies for the control stability analysis of high-performance, high angle-of-attack aircraft such as HARV (F18). Past (reported in our Phase 1, 2, 3 progress reports) summarized more details final provided. While emphasis on control, other tasks associated model development, system identification, analysis, simulation are performed some detail well. An overview various models that were investigated different purposes an approximate reference adaptation, well another accurate rigid-body longitudinal motion Only a very cursory was made relative type 8 (flexible body dynamics). Standard airframe dynamics (type 7) with available modified F18 derivatives, thrust vectoring, actuator dynamics, constraints utilized simulated flight evaluation derived controller performance all cases studied.
