Abstract

In this study, a counter-flow methane reforming solid oxide fuel cell (MR-SOFC) system is proposed. Based on the response data of the system, a nonlinear least squares (NLS) identification method is used to identify the state space model, and a Kalman filter-based model prediction control (KF-MPC) is developed in SIMULINK. Finally, the co-simulation framework of Modelica/SIMULINK is developed to investigate the control performance of KF-MPC. The results show that the tracking accuracy and speed for the KF-MPC system are superior to those of proportional-integral-derivative (PID) in large-scale load changes and load fluctuations. The shortest settling time (tst) for net output power (Pnet) is 15s, which is only 24.19% of that of the PID in large-scale load changes. During load fluctuations, the maximum value of the root mean square error (RMSE) for Pnet in KF-MPC is 0.0372 kW, lower than that of PID (0.0948 kW) and only 39.23% of it. The tst in the KF-MPC system is 7s, much lower than the 285s in PID, at the step change of SOFC cathode inlet temperature (Tin). A large overshoot of Tin occurs in the PID system, and its RMSE (2.23 K) is higher than that (0.42 K) of the KF-MPC system. The maximum temperature gradient (max|ΔTPEN|) of the SOFC in the KF-MPC system is 19.94 K/cm, smaller than that of the PID. The temperature change rate of each node of the SOFC in the KF-MPC system is significantly smoother and the system operates more reliably during the control process.
