Model predictive control of dimethyl ether combustion in a jet stirred reactor under low temperature conditions

This paper deals with the control of instabilities and oscillations during the combustion of dimethyl ether (DME) in a continuous jet stirred reactor (JSR). A Model Predictive Control (MPC) is applied to keep the reactor in a steady state at low temperature combustion conditions. The full chemical state of the system consisting of temperature and species concentration is reconstructed from a temperature and a CH concentration signal by an extended Kalman filter. For prediction within the MPC and the filter, a physical model of the JSR including a full combustion reaction mechanism is presented.
