摘　　要：讨论了在功率需求快速变化下质子交换膜燃料电池的动态响应性能。将带有参数在线估计的smith预估和自适应模糊PID控制相结合,应用于PEMFC的输出控制。使用MATLAB对控制系统进行仿真,并进行了相应的抗干扰及鲁棒性仿真实验。仿真结果表明,实施的控制方案具有较好的鲁棒性和自适应能力。This paper discusses the PEMFC dynamic characteristics under quick variance of power demand. Smith estimate with parameter online identified is combined with self-adapted fuzzy PID control, which is applied to the output control of PEMFC. MATLAB is used to simulate the control system, and the corresponding anti-disturbance and robustness simulations are also implemented. The simulation result reveals that the implemented control schemes have relatively better robustness and self-adaptable ability.
