摘要
利用高压空压机测试平台,通过相关技术辨识了高压燃料电池空气供应子系统的传递函数矩阵.基于前馈补偿解耦技术实现了空气流量和背压的相对独立控制.实验和仿真结果表明,该策略在较大范围内具有较好的鲁棒性.
Based on a platform of a high pressure air compressor,the transfer function matrix of the air supply subsystem for high pressure proton exchange membrane fuel cell （PEMFC） is identified and then the air flow and back pressure is decoupled via feed-forward compensation decoupling control technique.Both the results of experiment and simulation show that the proposed controller can really achieve the decoupling control of air flow and back pressure,and it also has good robust performance in a large range of working condition.
