Abstract
This thesis addresses the design and analysis of discrete
lateral autopilots for application to BTT missiles.
The first part reviewed the classical design and analysis of
the continuous uncoupled yaw and roll channels as developed in
[Ref. 6]. Then, applying analog-to-digital conversion, the
corresponding discrete autopilots were designed and analyzed in
terms of their transient responses.
The second part utilized modern control design techniques for
the single-input discrete lateral autopilots. At first, assuming
availability of all states for feedback purposes, a discrete
state-feedback autopilot was obtained. Next, since the state
vector is not always available to direct measurement, as estimator
was introduced to implement control. The state-feedback and
estimator designs were analyzed for both lateral channels and
found to have satisfactory time responses.
Finally, coupling the discrete pitch and roll channel
autopilots, a state-feedback and estimator were designed and
found to be robust.
