Embodiment Construction
[0040] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0041]The invention treats the solid oxide fuel cell as a multi-variable object with two inputs and two outputs under load resistance disturbance, adopts multi-variable predictive control technology, and dynamically optimizes the opening of hydrogen and air intake valves, thereby dealing with the relationship between fuel utilization rate and output voltage Coupling problem. By expanding the prediction model of disturbance observation, the dynamic deviation caused by load disturbance is quickly eliminated, and the anti-interference ability of solid oxide fuel cells is improved. On the other hand, by setting interval constraints on the amplitude and rate of the intake va...
