Abstract: | The paper deals with continuous-time nonlinear adaptive control of a continuous stirred tank reactor (CSTR). Control strategy
is based on the application of a controller consisting of a linear and a nonlinear part. The static nonlinear part is derived
as an inversion and exponential approximation of measured or simulated input-output data. Design of the dynamic linear part
is based on an approximation of nonlinear elements in the control loop by a continuous-time external linear model with directly
estimated parameters. In the control design procedure, polynomial approach with the pole assignment method was used. The nonlinear
adaptive control was tested by simulations on a nonlinear model of a CSTR with a consecutive exothermic reaction. |
