This work presents a method for selecting the gain parameters of a C* control law for an aircraft's
longitudinal motion. The design incorporates various handling quality requirements involving modal, time-
and frequency-domain criteria that were fixed by the aircraft manufacturer. After necessary model order-
reductions, the design proceeds in essentially two-step
s: Stability Augmentation System (SAS) loop design
and Control Augmentation System (CAS) loop design. The approach partly relies on the use of guardian
maps to characterize, in each case, the set of gain parameters for which desired handling quality requirements
are satisfied. The approach is applied throughout the full flight envelope of a business jet aircraft and yields
satisfactory results.
