A Coordinating Control Strategy for Autothermal Fuel Reforming Systems

In this paper, a control-oriented nonlinear model is developed for an autothermal reformer-based fuel process system. By trajectory planning for one of the system states, a coordinating control algorithm is proposed for the three input flow rates to track/regulate the temperature and hydrogen production of the autothermal reformer. Stability analysis is provided to show a local uniformly ultimately bounded tracking result. Simulation results illustrate the performance of the proposed control algorithm.
