基于模糊控制的水下无人动力平台PEMFC稳压系统仿真
Simulation of PEMFC Voltage Stabilization System for Underwater Unmanned Power Platform Based on Fuzzy Control
摘要
Abstract
Aiming at the demand of underwater unmanned power platform for an efficient and stable energy system,this paper focused on the problem of strong nonlinearity and easy fluctuation of the output voltage of proton exchange membrane fuel cell(PEMFC)and proposed a DC-DC converter voltage stabilization strategy based on the fuzzy proportional-integral-derivative(PID)adaptive control.Due to the strong nonlinear characteristics of the output voltage of the PEMFC and its fluctuation trend,the traditional control methods have limitations in the dynamic response and robustness.Therefore,a mathematical model of PEMFC,including Nernst voltage and activation,ohmic,and concentration loss and a Boost boost circuit model were established to analyze the voltage fluctuation mechanism.A fuzzy PID controller was designed,with a rule base that deeply coupled the PID control principle with the nonlinear characteristics of PEMFC,which realized the online dynamic self-tuning of PID parameters to optimize the duty cycle of the DC-DC converter in real time.The simulation results show that compared with the traditional PID control,the fuzzy PID control can shorten the system regulation time,and the steady-state error tends to be close to zero;the output voltage fluctuation range is narrowed to within±0.5 V under the sudden current change condition,and the duty cycle response is more accurate.The fuzzy PID adaptive strategy significantly enhances the dynamic response speed and robustness of the system,providing a reliable theoretical cornerstone and solution for the efficient and stable operation of the energy system of the underwater unmanned platform.关键词
