针对SOFC系统的非线性、大滞后和干扰等特点,提出使用模糊GPC算法实施对SOFC的闭环控制.这种方法使得SOFC的输出电压始终保持在一定范围内,并收敛到恒定的数值.该方法还提高了SOFC输出功率的跟踪性能.仿真结果验证了这种方法的有效性.
By considering the nonlinearity, large delay and disturbance in solid oxide fuel cell (SOFC) dynamics, a fuzzy generalized predictive control is applied. This control method makes the output voltage of SOFC maintain within a certain rage, and let the voltage finally converge to a constant value. This controller also enhanced the tracking performance for the output power. Simulation results have demonstrated the effectiveness of this control approach.
