An Adaptive Observer Design for Takagi-Sugeno type Nonlinear System. (arXiv:1704.05361v1 [math.OC])
来源于:arXiv
Takagi-Sugeno (T-S) type of polytopic models have been used prominently in
the literature to analyze nonlinear systems. With the sector nonlinearity
approach, an exact representation of a nonlinear system within a sector could
be obtained in a T-S form. Hence, a number of observer design strategies have
been proposed for nonlinear systems using the T-S framework. In this work, a
design strategy for adaptive observers is presented for a type of T-S systems
with unknown parameters. The proposed approach improves upon the existing
literature in two folds: reduce the computational burden and provide an
algorithmic procedure that would seamlessly connect the state estimation and
parameter estimation parts of the observer design. Lyapunov approach is used
for the stability analysis and the design procedure. The results are
illustrated on a simulation example. 查看全文>>
