Subjects related to a robust multivariable autopilot design are examin
ed in this paper. First, a canonical robust control design formulation
is introduced and is illustrated by formulating an integrated autopil
ot design problem, This formulation addresses the considerations of mi
ssile command following, model parameter variations, actuator dynamics
, flexible dynamics, and parasitic feedback effects. Then, three robus
t 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. T
he simulation shows that the designs achieve good response against sig
nificant kinematic and inertia couplings and aerodynamic parameter var
iations.
