| description | Unfortunately, the major group of the systems in industry
has nonlinear behavior and control of such processes with conventional
control approaches with fixed parameters causes problems and suboptimal or unstable control results. An adaptive control is one way to how we
can cope with nonlinearity of the system. This contribution compares
classic adaptive control and its modification with Wiener system. This
configuration divides nonlinear controller into the dynamic linear part and
the static nonlinear part. The dynamic linear part is constructed with
the use of polynomial synthesis together with the pole-placement method
and the spectral factorization. The static nonlinear part uses static analysis of the controlled plant for introducing the mathematical nonlinear
description of the relation between the controlled output and the change
of the control input. Proposed controller is tested by the simulations
on the mathematical model of the continuous stirred-tank reactor with
cooling in the jacket as a typical nonlinear system. |
