A fixed compensation design theory is presented for achieving flight control performance, despite one or more simultaneous failures, hardover and varying flight conditions. No identification is used. The theory is a natural extension of Quantitative Feedback Theory (QFT) for uncertain systems, and clearly reveals the cost of feedback needed. This enables the designer to make intelligent trade-offs between fixed compensation, scheduling and identification-adaptation. Identification, when it is necessary, can be done more slowly and accurately if a QFT design is made so the system in at least stable over many simultaneous failures. The theory is applied to the YF16CCV model with elevators and flaperons for pitch and roll rate control.
