摘要：

随着氢燃料电池汽车行业的发展，质子交换膜燃料电池发动机控制成为研究的重点。空气路进气压力的精准控制是延长燃料电池发动机寿命和提高效率的关键。因此，本文主要研究空气进气系统的压力控制。首先，建立空气进气压力的数学模型；其次，考虑模型的不确定性和外部扰动，设计扰动观测器估计和补偿这些不确定性的影响；再次，基于建立的数学模型提出一种新型滑模控制方法实现空气进气压力的精准控制；最后，通过4种仿真工况验证空气路压力控制策略的有效性。

关键词: 质子交换膜燃料电池发动机, 空气进气压力控制, 扰动观测器, 新型滑模控制

Abstract:

With the development of the hydrogen fuel cell vehicles industry， the control of proton exchange membrane fuel cell engine has become the focus of research. To improve the life and efficiency of fuel cell engines， the air supply pressure should be precisely controlled. Therefore， we primarily research the control of air supply pressure in this paper. Firstly， the modeling of air supply pressure is established. Secondly， considering the existence of model uncertainty and disturbances， we design the disturbance observer to estimate and compensate this influences. Thirdly， a new slide mode control method is proposed to achieve accurate pressure control based on the established mathematical model. Finally， the effectiveness of the air supply pressure control strategy is verified through four simulation conditions.

Key words: proton exchange membrane fuel cell engines, air supply pressure control, disturbance observer, new slide mode control
