Convert affine parameter-dependent models to polytopic models

Syntax

• polsys = aff2pol(affsys) 
  

Description

aff2pol derives a polytopic representation polsys of the affine parameter- dependent system

(5-1)

(5-2)

where p = (p1, . . ., pn) is a vector of uncertain or time-varying real parameters taking values in a box or a polytope. The description affsys of this system should be specified with psys.

The vertex systems of polsys are the instances of Equation 5-1 and Equation 5-2 at the vertices pex of the parameter range, i.e., the SYSTEM matrices

for all corners pex of the parameter box or all vertices pex of the polytope of parameter values.
