In this paper,a new approach to gain-scheduling of robust autopilot was proposed for morphing guided aerial bombs in a bank-to-turn (BTT) mode.The nonlinear dynamic model was established and anticipant performance criterions were given firstly.Feedback robust BTT autopilot of 3-channel was designed independently for selected operating points in order to restrain cross-channel coupling disturbances and aerodynamic perturbations.Then,the sweepback and mach number were selected to schedule the control gains iteratively based on guardian maps for ensuring all closed-loop poles to locate inside the desired region.The method proposed here attempted to extend the performance of an initial design obtained for a single arbitrary point to the whole linearized domain while maintaining expected stability over the entire range of sweepback.We carried out a number of time- and frequency-domain analysis procedures on the resulting designs and assessed the performance on a nonlinear simulation.The numerical simulations showed that the method proposed applied on the autopilot design and had better tracking performance.
