| description | The aircraft pitch axis stability augmentation system was analyzed using sum of squares optimization. The nonlinear dynamics of the pitch axis of a fictitious Aircraft - the Robust Civil Aircraft Model (RCAM) was considered. A LTI dynamic inversion based control law for the short period dynamics of the AC pitch axis at a particular trim configuration which is given by a particular flight condition was designed. The stability region for the LTI controlled short period dynamics model of the A/C was determined. The stability regions of the LTI controlled short period + phugoid dynamics model of the A/C were determined. The stability regions were computed using SOSTOOLS which solves a Sum-of-Squares Optimization problem. |
