Abstract: |
A
Continuous Stirred-Tank Reactor is typical system with nonlinear behavior and
lumped parameters. The mathematical model of this type of reactor is described
by the set of nonlinear ordinary differential equations that are easily
solvable with the use of numerical methods. The big advantage of the computer
simulation is that once we have reliable mathematical model of the system we
can do thousands of simulation experiments that are quicker, cheaper and
safer then examination on the real system. The control approach used in this
work is a hybrid adaptive control where an adaptation process is satisfied by
the on-line recursive identification of the External Linear Model as a linear
representation of the originally nonlinear system. The polynomial approach
together with the Pole-placement method and spectral factorization satisfies
basic control requirements such as a stability, a
reference signal tracking and a disturbance attenuation. Moreover, these
methods produce also relations for computing of controller’s parameters. As a
bonus, the controlled output could be affected by the choice of the root
position in the Pole-placement method. The goal of this contribution is to
show that proposed controller could be used for various outputs as this
system provides five possible options. |
