摘　　要：为实现对PEMFC-Boost变换器非线性行为的有效控制,改善系统输出性能,依据滑模控制基本原理,设计了PEMFCBoost变换器系统滑模控制电路。根据所设计的控制电路,在MATLAB软件中搭建了滑模控制仿真电路,将滑模控制仿真模型与PEMFC-Boost系统仿真相结合,形成了PEMFC-Boost变换器滑模控制仿真模型。最后,通过仿真对比分析了滑模控制与一般PI控制的控制效果,研究了系统电压扰动和负载扰动对滑模控制效果的影响。In order to realize the effective control of the nonlinear behavior of PEMFC-Boost converter and improve the system output performance,based on the basic principle of sliding mode control,the sliding mode control circuit of PEMFC-Boost converter system is designed. According to the control circuit designed,the sliding mode control simulation circuit is built in MATLAB software. The sliding mode control simulation model is combined with PEMFC-Boost system simulation to form a sliding mode control simulation model of PEMFC-Boost converter. Finally,the control effect of sliding mode control and general PI control is analyzed by simulation,and the influence of system voltage disturbance and load disturbance on sliding mode control effect is studied.
