摘要:

固体氧化物燃料电池(Solid Oxide Fuel Cell,SOFC)因其高效率、零污染而被誉为21世纪最有潜力的发电技术之一。本文针对SOFC热管理系统的多级热容积大滞后和强干扰等特点,运用一种有效的控制方法——串级控制来对SOFC进行闭环控制。该控制方法能很好的解决多级热容积这一滞后动态过程带来的响应慢、调节时间过长等控制难题,并能有效抑制负载变化引起的干扰。最后通过仿真结果说明该控制方法的有效性。

Solid Oxide Fuel Cell is known as the most promising power generation technologies in the 21st century because of its high efficiency and zero pollution. For the multi-level thermal capacity lag and the strong interference of SOFC thermal management system, an effective control method (cascade control) is presented to solve it in this paper. The method is a good solution to the problems such as slow response and too long regulation time caused by the multi-level thermal capacity lag, and it also can effectively inhibit the interference caused by the load fluctuation. The simulation results illustrate the effectiveness of the control method.
