Robust bank-to-turn missile autopilot design

Subjects related to a robust multivariable autopilot design are examined in this paper. First, a canonical robust control design formulation is introduced and is illustrated by formulating an integrated autopilot design problem. This formulation addresses the considerations of missile command following, model parameter variations, actuator dynamics, flexible dynamics, and parasitic feedback effects. Then, three robust autopilot designs for the HAVE DASH II missile system are executed. The controllers are solved using the generalized Hamiltonian approach which unifies a class of robust control designs in the same framework in terms of the formulation, data structure, and solution algorithm. The simulation shows that the designs achieve good response against significant kinematic and inertia couplings and aerodynamic parameter variations.
