Commonly-Used Nomenclature
This manual uses the following general nomenclature:
•
Matrix variables are generally denoted with capital letters; vectors are
represented in lowercase.
•
G
(
s
) is used to denote a transfer function of a system where
s
is the
Laplace variable.
G
(
q
) is used when both continuous and discrete
systems are allowed.
•
H
(
s
) is used to denote the frequency response, over some range of
frequencies of a system where
s
is the Laplace variable.
H
(
q
) is used to
indicate that the system can be continuous or discrete.
•
A single apostrophe following a matrix variable, for example,
x
',
denotes the transpose of that variable. An asterisk following a matrix
variable (for example, A*) indicates the complex conjugate, or
Hermitian, transpose of that variable.
