An isothermal reactor is a typical member of nonlinear processes. The mathematical modeling and computer simulations are tools widely used nowadays for their advantages over the experiment on the real system. The mathematical model of the surveyed isothermal reactor is described by the set of five ordinary differential equations which could be easily programmed and solved by mathematical software, e.g. Matlab. The paper shows a procedure for designing and controlling of this type of the reactor. The design of an adaptive controller uses a polynomial approach together with the linear-quadratic approach and the spectral factorization. It means that this controller satisfies basic control requirements. The adaptivity of the system is satisfied by the recursive identification of the external linear model.

STRESZCZENIE W artykule przedstawiono model układu regulacji dynamiki reaktora zbiornikowego przepływowego w syntezie metanolu w układzie trójfazowym. Symulację reaktora przeprowadzono zarówno dla stanów ustalonych jak i nieustalonych. Obliczono współczynnik efektywności do osiągnięcia maksymalnej wydajności produktu z jednostki objętości reaktora. Z symulacji dynamiki reaktora w zamkniętej pętli regulacji otrzymano dane służące nastrojeniu regulatora PID (regulator proporcjonalno-całkująco-różniczkujący). Wyniki regulacji procesowej zapewniają optymalną zdolność produkcyjną reaktora wraz z eliminacją miejscowych przegrzań czy nagłych wzrostów temperatury.Słowa kluczowe: regulator PID, symulacja dynamiczna, reaktor zbiornikowy przepływowy MODELLING AND CONTROL OF CONTINUOUS STIRRED TANK REACTOR WITH PID CONTROLLER ABSTRACTThis paper presents a model of dynamics control for continuous stirred tank reactor (CSTR) in methanol synthesis in a three-phase system. The reactor simulation was carried out for steady and transient state. Efficiency ratio to achieve maximum performance of the product per reactor unit volume was calculated. Reactor dynamics simulation in closed loop allowed to received data for tuning PID controller (proportional-integral-derivative). The results of the regulation process allow to receive data for optimum reactor production capacity, along with local hot spots eliminations or temperature runaway.

The role and importance of the simulation rises with the increasing speed of computers and simulation tools provided nowadays. Safety and less money and time demands gives a computer simulation big advantage over the experiments on a real system or its model. The paper deals with simulation of an adaptive control on a nonlinear system represented by a Continuous Stirred Tank Reactor (CSTR). This system is mathematically described by a set of Ordinary Differential Equations (ODE) which are first solved numerically to obtain steady-state and dynamic behaviour of the system. The adaptive control is based on the recursive identification of an External Linear Model (ELM) as a representation of the originally nonlinear system. The polynomial approach together with the pole-placement method gives sufficient control results although the system has negative control properties.
