of a multivariable nonlinear continuous stirred tank reactor (CSTR) via a moving model is presented. Both cooling and heating media are used to manipulate the concentration and the temperature. The system can be operated around an unstable steady-state or across a separatrlx from a low-temperature p

β¦ Synopsis
Open nonlinear chemical systems can show a variety of behavioral patterns depending on the operating values of the parameters and intrinsic system features. In general, for different sets of parameter values, a nonlinear system can operate at a steady state, or perform simple/complex oscillations or even chaotic motions . Controlling these systems with a view to operate them under favorable conditions poses considerable challenges. The use of conventional PID control methods (which do not use a mathematical process model) seems to be inadequate, since they perform well only for linear and mildly nonlinear systems. For systems with strong nonlinearity, better methods are needed; in particular, internal model control (IMC) strategies have been studied (
