Simulation of nonlinear adaptive control of a tubular chemical reactor
Authors: Petr Dostal, Jiri Vojtesek, Vladimir Bobal
Abstract
The paper presents design and simulation results of nonlinear adaptive control of a tubular chemical reactor. The control strategy is based on factorization of the controller on an adaptive dynamic linear part and a static nonlinear part. The static nonlinear part is derived using simulated steady-state characteristics of the process and its subsequent inversion and approximation. The linear part consisting of two linear feedback controllers results from an approximation of nonlinear elements in the control system by an external linear model with recursively estimated parameters. The control law is derived via the polynomial approach and the pole placement method.
