0.12 Kinematic Types<br />

A Reference value of parameter (A)<br />

A ~ Measured value of parameter (A)<br />

 Filtered value of parameter (A)<br />

A ( Optimised value of parameter (A)<br />

A Mean value of parameter (A)<br />

Kinematic types may be omitted when it is clear that all the data involved is<br />

of the same type. Strict typing is only required when the different types<br />

interact, as for example, in the computation of system errors.<br />

0.13 Time Rate of Change<br />

A & First derivative with respect to time (if (A) is position, then<br />

velocity)<br />

A & Second derivative with respect to time (if (A) is position, then<br />

acceleration)<br />

A & Third derivative with respect to time (if (A) is position, then<br />

jerk)<br />

0.14 General Vector Notation<br />

0.14.1 Vector Components<br />

A general n-dimensional vector behaves as an (n,1) matrix (n-rows,1column),<br />

however, it is denoted by an underline and its components are<br />

numbered (1,2,…n),<br />

A superscript “T” is used to indicate vector transposition thereby<br />

maintaining a clear distinction between row and column vectors. By<br />

definition, all general n-vectors denoted by an underlined kernel letter, here<br />

(V), are column vectors. A row vector is denoted explicitly using the<br />

superscript “T”, for example V T , which behaves as an (1,n) matrix.<br />
