| 摘 要： | 质子交换膜燃料电池(PEMFC)电堆的温度系统是一类存在非匹配摄动和外干扰的多输入多输出非线性系统,且工作温度对电池的输出性能有较大的影响.为削弱此负面影响,采用输入输出线性化方法与变结构控制相结合的智能控制方法.仿真试验结果表明,温度对参数摄动和负荷干扰具有很强的鲁棒性,动态特性好,渐近稳定;温度得到稳定控制之后,设计衰减整定PID参数的常规控制器可较好地改善电池的输出性能.

| Abstract: | The temperature system of proton exchange membrane fuel cell(PEMFC) stack is a nonlinear multi-input and multi-output system with unmatched problem and external disturbance.And the output performance of fuel cell is affected by operation temperature.An intelligent control algorithm of input/output linearizing(I/O L) combined with variable structure control(VSC) was used to weaken the negative effection.The simulation and experimental results provide quite satisfactory performance with parameter perturbation and external disturbance such as robust,dynamic character and asymptotic stability.After the temperature is controlled well,output performance of PEMFC stack is adjusted with good effect by PID controller tuned with decay-curve law. |
