Abstract:
The design of various feedback
controllers, optimal controllers require the
information about all the states present in the
system. Not all the states in the system will be
available for direct measurement. In order to
estimate all the states of the system the observers
are designed. In this paper the state estimation
problem of the CSTR is considered, the
observers used include Luenberger Observer,
Kalman Observer, and Sliding Mode Observer.
The states that are estimated using the observers
are utilized by the state feedback controllers and
the optimal controllers, to ensure the
convergence of the states to the equilibrium
point. The designed observers had the residuals
converging to zero in finite time and the
comparison in terms of estimation errors
resulted in better performance of the sliding
mode observer.
