Resumen:
In this paper, a simple observer design scheme is proposed for a class
of 1-D semi-linear parabolic distributed parameter systems with
in-domain measurement. The main idea of the design resides in imposing
the measurement on the observer dynamics in a similar way as it is done
in the finite-dimensional reduced order observer design. For the
distributed system this is achieved through an additional algebraic
constraint in the domain instead of an output injection mechanism.
Correspondingly, the observer convergence is not induced by the
correction scheme, but by the sensor location and the system parameters,
and thus amounts on the underlying detectability property rather than
the system observability. Possible applications to the case of unknown
inputs are discussed. The proposed estimation approach is illustrated
and tested through simulations with two representative examples: an
unstable diffusive linear system with Dirichlet boundary conditions, and
a stable isothermal single-species nonlinear tubular reactor with
non-monotonic kinetics and Robin-Newman (i.e., Danckwerts) boundary
conditions.
