Use of nonlinear theory in adaptive control of chemical reactor
Authors: Jiri Vojtesek, Petr Dostal
Abstract
This contribution is focused on the improvement of the adaptive control of the nonlinear process. The method used here is based on the separation of the controller to the linear and nonlinear part where the nonlinear part is comes from the steady-state analysis and the linear part uses the External Linear Model (ELM) as a linear representation of the nonlinear parts in the loop. Parameters of the ELM are estimated recursively with the use of delta models as a special types of discrete- time models. The controller synthesis uses a polynomial approach with the pole-assignment method which satisfies basic control requirements such as stability, a reference signal tracking and disturbance attenuation. The proposed methods are tested by the simulations on a mathematical model of the Continuous Stirred Tank Reactor (CSTR) as a typical member of nonlinear systems with lumped parameters.
