Abstract: |
Motivated
by the rich dynamics of chemical processes, we present a gain scheduled
control strategy for a pH neutralization occurring inside continuously
stirred tank reactor built on a linearization of a nonlinear state equation
about selected operating points. Firstly, we address the problem of a
selection of scheduling variable. Based on this, an extra scheduling
mechanism is presented to simulate the behavior of a nonlinear process using
a linear model. Specifically, the proposed step aims at extending the region
of validity of linearization by introducing a parametrized
linear model, which enables to construct linear controller at each point.
Finally, the parameters of resulting family of linear controllers are
scheduled as functions of the reference variable, resulting in a single
scheduling controller. |
