Abstract:	The goal of this contribution is to present simulation re-sults of the adaptive control of the tubular chemical re-actor as a typical equipment used in the industry. The mathematical model of the tubular reactor is described by a set of nonlinear partial differential equations. The numerical solution of such model is not trivial but the combination of the Finite difference and Rung-Kutta’s method can be used for this task. The adaptivity of the controller is satisfied by the recursive identification of the external linear model as a linear representation of the originally nonlinear system. Control synthesis employs a polynomial approach together with the con-nection to the Pole-placement method and the spec-tral factorization satisfies basic control requirements and provides not only the structure of the controller but also computational relations. There are compared results for control systems with one degree-of-freedom (1DOF) and two degrees-of-freedom (2DOF).
