Problems solved by technology

At the same time, solid oxide fuel cells also have constraints on hydrogen and air intake valves and fuel utilization, making traditional control methods unable to achieve more satisfactory control effects and economic effects
In addition, due to the existence of disturbance, measurement noise, and uncertainty, the controller will have a certain interference effect, making it difficult for the traditional controller to obtain good control quality.

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...

Abstract

The invention discloses a fuel cell anti-interference control method with high speed, good safety and good decoupling performance. According to the characteristics that solid oxide fuel cells experience frequent load interferences and a system has low response speed and great coupling performance, and optimal control for the solid oxide fuel cells is achieved through extension state observation, operational restraint setting and multi-variant prediction control algorithm. By amplifying a prediction model in disturbed form, the issue with low load interference response of the fuel cells is solved; by setting amplitude limit speed for an intake valve and operation restraints on reasonable fuel usage, failure of the valve and battery gas shortage are effectively avoided; according to the characteristic of great coupling of fuel usage ratio and output voltage, a multi-variant prediction control algorithm is used to achieve decoupling during dynamic optimizing. The fuel cell anti-interference control method provided herein has the advantages that hydrogen and air intake volumes are precisely optimized, the influence of load disturbances upon output voltage is quickly inhibited, fuel usage ratio is increased, and operational safety of the valve and the fuel cells are guaranteed.

Description

technical field [0001] The invention relates to a fuel cell anti-interference control method with fast, safe and decoupling performance, and belongs to the technical field of automatic control of new energy utilization. Background technique [0002] With the rapid development of economy and society, people's utilization of resources is also increasing day by day, and the excessive use of conventional energy (coal, oil, natural gas) has caused serious environmental problems. Traditional fossil fuel power generation converts chemical energy into thermal energy and then uses mechanical energy to generate power. This is limited by the Carnot cycle and the efficiency is not high. As an advanced energy utilization technology, the fuel cell directly converts the chemical energy in the fuel into electrical energy through an electrochemical reaction, and has the characteristics of high efficiency, cleanliness and safety. All countries in the world have invested manpower and funds to...
