<p>Redundant controllers are being designed to provide improved
system reliability to meet the needs of various applications. In some
implementations of these systems unacceptable system transients have
occured when a single-controller failure occurs. The problem has
been treated using case-by-case correction which is not sufficiently
general in application to meet the needs of systems which may be
user-programmed.
Redundant control systems generalized as ideal and nonideal
using two specific voting schemes are examined to gain insight into
theoretical characterization of their performance under single-point
failure modes and the limitations of applicability for the
characterizations. State-model computer simulation is used to
demonstrate the characterizations. A suggested direction for a
general solution to the problem based on the chatacterizations is
described.</p> / Master of Science
