Abstract: |
The paper deals with design
and simulation of nonlinear adaptive control of a shell and tube heat
exchanger. The method is based on factorization of the controller on a nonlinear
static part and an adaptive linear dynamic part. The nonlinear static part is
derived using inversion and subsequent exponential approximation of simulated
or measured steady-state characteristics of the exchanger. The linear dynamic
part is then obtained from an external linear model of nonlinear elements of the
closed-loop. The parameters of the external linear model are recursively
estimated via a corresponding delta model. The control law in the 1DOF and
2DOF control system structures is derived using the polynomial approach. |
