A Method for Including Control Effector Interactions in the Control Allocation Problem (Preprint)

摘要: Abstract : Much emphasis has been placed on over-actuated systems for air vehicles. Over-actuating an vehicle provides a certain amount of redundancy the flight control system, thus potentially allowing recovery from off-nominal conditions. Due to this redundancy, allocation algorithms are typically utilized compute unique solution problem. As number effectors increases, likelihood occurrence effector interactions increases. For example, deflection aerodynamic surface that is upstream another may cause forces and moments produced by downstream differ those when not deployed. Another example can be found launch vehicles use combination differential throttles gimballed nozzles attitude control. The effectiveness clearly influenced engine thrust. above examples interaction In work, method devised, which utilizes linear programming methods in iterative framework, take into account interactions. While nonlinear techniques could directly applied such problems, lack convergence guarantees precludes their critical systems. appealing because optimal each sub-problem determined finite time.
