Weighting pattern

From Wikipedia, the free encyclopedia

A weighting pattern for a linear dynamical system describes the relationship between an input and output . Given the time-variant system described by

,

then the output can be written as

,

where is the weighting pattern for the system. For such a system, the weighting pattern is such that is the state transition matrix.

The weighting pattern will determine a system, but if there exists a realization for this weighting pattern then there exist many that do so.[1]

Linear time invariant system

[edit]

In a LTI system then the weighting pattern is:

Continuous

where is the matrix exponential.

Discrete
