| Sumario: | Considering the Linear Parameter Varying (LPV) systems of discrete time, in this paper an approach for
the synthesis of robust Proporcional+Integral Observers (PIO) is presented. From LPV systems characterized with
polytopical uncertainties, the method of design is based on considering a dynamics extended of the typical PIO,
in order to transform the design of the matrices of the dynamics of the observer, as a design of the gain of Static
Output Feedback (SOF) of a problem of robust control. Under these conditions and from the norms
H
2
=
H
1
described as Linear Matrix Inequalities (LMI), the criteria to obtain the gain in the SOF problem are established;
taking into account performance indices in
H
2
and
H
1
, under the presence of uncertainties and disturbances. |
