Adaptive Control of Chemical Reactor

This paper deals with the adaptive control of the nonlinear process represented by the continuous stirred tank reactor (CSTR). This chemical equipment is widely used in the chemical industry for production of various chemicals and drugs. Computer simulation which is used in this work has several advantages over the experint on the real model – it saves costs, reduces dangerousity and speed up experiments. The paper presents one approach to the control of the chemical reactor based on the choice of the external linear model (ELM) of the originally nonlinear process parameters of which are identified recursively and parameters of the controller are then adopt to these estimated ones. The polynomial approach together linear quadratic (LQ) approach used for the controller synthesis show good control results although the system has negative control properties.
