Function File: est = estim (sys, l)

Function File: est = estim (sys, l, sensors, known)

Return state estimator for a given estimator gain.

Inputs

sys

LTI model.

l

State feedback matrix.

sensors

Indices of measured output signals y from sys. If omitted, all outputs are measured.

known

Indices of known input signals u (deterministic) to sys. All other inputs to sys are assumed stochastic (w). If argument known is omitted, no inputs u are known.

Outputs

est

State-space model of estimator.
