Abstract : Presented here is an implicit model following design technique, based on linear optimal control, that is particularly effective for complicated flight control situations with many controls and with difficult design specifications. The procedure involves defining the quadratic performance index to be minimized in such a way that precludes on-board generation of desired handling quality model dynamics. This complex performance index, which in general will contain cross coupled state and control variables, yields feedback and feedforward control gain solutions which implicitly force the actual system to follow the desired response.
