Adaptive Control of Tubular Chemical Reactor
In this paper the simulation results of the adaptive control inside the tubular chemical reactor with counter-current cooling in the jacket is shown. The adaptive controller is based on the choice of the External Linear Model as a linear representation of the originally nonlinear system parameters of which are identified recursively. The polynomial method together with spectral factorization an...
متن کاملIncorporation of Statistical Distributions of Particle Properties in Chemical Reactor Design and Operation: the Cooled Tubular Reactor
Pellet heat and mass transfer coefficients inside packed beds do not have definite deterministic values, but are stochastic quantities with a certain distribution. Here, a method is presented to incorporate the stochastic distribution of pellet properties in reactor design and operation models. The theory presented is illustrated with a number of examples. It is shown that pellet-scale statisti...
متن کاملSimulation Of Adaptive Control Of A Tubular Chemical Reactor
The paper deals with continuous-time adaptive control of a tubular chemical reactor with the countercurrent cooling as a nonlinear single input – single output process. The nonlinear model of the reactor is approximated by an external linear model with parameters estimated via corresponding delta model. The control system structure with two feedback controllers is considered. The resulting cont...
متن کاملSimulation of Adaptive Control Applied on Tubular Chemical Reactor
Simulation has a big importance nowadays when the speed of computers grows rapidly and the price is on the other hand decreasing. The paper is focused on the simulation of the steady-state and dynamic behaviour of the nonlinear system represented by the tubular chemical reactor with the co-current and countercurrent cooling in the jacket. These analyses are then used for the choice of the suita...
متن کاملDevelopment of Tubular Chemical Reactor Models for Control Purposes
A generalized nonlinear mathematical model for fixed-bed tubular chemical reactors with cooling is proposed. The model is suitable for simulation experiments. A strategy, focused on simplifying and adapting the "primary" model to control applications is shown. This procedure is driven through the so-called "pseudohomogeneous" form of the model until a final description which is linear and relat...
