On‐line solutions are desirable for dealing with control failure and reconfiguration. Assuming the nature of the control failure can be identified, the failed control effector can be removed from the control effectiveness matrix, or the B matrix can be modified in some suitable way to accommodate the failure. Off‐line solutions are pre‐computed in whole or in part, but in either case, require foreknowledge of, at a minimum, the control effectiveness matrix B. The idea of preferred solutions first arose when certain control allocation algorithms exhibited a phenomenon referred to as ‘windup’. Edge‐ and facet‐searching methods seek to remove the requirement to test edges or facets by generating them and checking for an intersection until the correct one is found. Linear programming is an extensively studied method of finding optimal solutions to linear sets of equations with constraints on some or all of the variables.
