摘　　要：基于固体氧化物燃料电池(SOFC)的基准非线性动力学模型,针对SOFC的负载跟踪和温度跟踪系统,设计了非线性滑膜控制器(SMC),并以模型预测控制器(MPC)作为对照。在设计控制器的过程中,以电池输入空气流量、电流变化率和氢气流率为操作变量。控制结果显示,SMC能更快地跟踪负载功率和温度阶跃变化,且在稳态状况下比MPC工作更稳定。Based on the benchmark nonlinear dynamic model of solid oxide fuel cell(SOFC),a nonlinear sliding film controller(SMC)is designed for the load tracking and temperature tracking system of SOFC,and compared with the model predictive controller(MPC).In the process of designing the controller,the battery input air flow rate,current change rate and hydrogen flow rate are taken as the operating variables.The control results show that SMC can track the step change of load power and temperature more quickly,and work more stable than MPC in steady state.
