Thermal modelling and control of hydrogen-oxygen combustor

The hydrogen-oxygen combustor represents an area of particular interest to temperature control. In this paper, we developed the thermal model of the hydrogen-oxygen combustor, which accounts for the interphase coupling. Using the model, the temperature distribution along the combustor is analyzed. In addition, we also proposed the new model predictive control (MPC) strategy for the outlet temperature control of the combustor. First, the relationship between the temperature at the combustor exit and the flow rate of coolant water is identified using support vector machine (SVM). Then, particle swarm optimization (PSO) is employed to solve the resulting optimization problem formulated by MPC. Simulation results demonstrate that the proposed MPC strategy can effectively regulate the temperature at the combustor exit to the set point.
