techniques. The general problem setup is explained together with 
known limitations; the rest is left to the references.

Throughout this document, bibliographic references are cited with 
bracketed entries. For example, a reference to [DoS81] corresponds 
to a document published by Doyle and Stein in 1981. For a table of 
bibliographic references, refer to Appendix A,

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.
