Simulation Study of 1DOF Hybrid Adaptive Control Applied on Isothermal Continuous Stirred-tank Reactor

Popis výsledku v původním jazyce

A Continuous Stirred-Tank Reactor is typical system with nonlinear behavior and lumped parameters. The mathematical model of this type of reactor is described by the set of nonlinear ordinary differential equations that are easily solvable with the use of numerical methods. The big advantage of the computer simulation is that once we have reliable mathematical model of the system we can do thousands of simulation experiments that are quicker, cheaper and safer then examination on the real system. The control approach used in this work is a hybrid adaptive control where an adaptation process is satisfied by the on-line recursive identification of the External Linear Model as a linear representation of the originally nonlinear system. The polynomial approach together with the Pole-placement method and spectral factorization satisfies basic control requirements such as a stability, a reference signal tracking and a disturbance attenuation. Moreover, these methods produce also relations for computing of controller’s parameters. As a bonus, the controlled output could be affected by the choice of the root position in the Pole-placement method. The goal of this contribution is to show that proposed controller could be used for various outputs as this system provides five possible options.
