研究目的
Modeling and control of a photovoltaic-fuel cell-battery hybrid vehicle system using fuzzy logic for power management.
研究成果
The simulation demonstrates that the hybrid system with a fuzzy logic controller effectively manages power distribution, particularly during peak loads where the photovoltaic cell provides additional support. The fuel cell's slow response is mitigated by the battery and PV integration, ensuring system stability and quick response. Future work could involve experimental validation and optimization for broader applications.
研究不足
The study relies on simulation-based modeling without experimental validation, which may not capture real-world complexities. The models are based on theoretical equations from literature, potentially limiting accuracy. The fuzzy logic controller's performance is tested only under specific load conditions, and scalability to other scenarios is not addressed.
1：Experimental Design and Method Selection:
The study involves modeling a hybrid energy system for electric vehicles using MATLAB/Simulink software, incorporating photovoltaic cells, proton exchange membrane fuel cells (PEMFC), and batteries. A fuzzy logic controller is designed to manage power distribution based on state of charge and power demand.
2：Sample Selection and Data Sources:
The models are based on equations from literature, with no specific real-world data mentioned; simulations use theoretical parameters.
3：List of Experimental Equipment and Materials:
Software tools include MATLAB/Simulink (Version 9.3, 2017) for modeling and simulation.
4：3, 2017) for modeling and simulation.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Models for PV, PEMFC, and battery are created in Simulink using defining equations. A fuzzy logic controller is implemented with inputs (SOC and power demand) and outputs (fuel cell power and PV power). Simulations are run with different load conditions (4 ohms and 2 ohms) to analyze system performance.
5：Data Analysis Methods:
Results are analyzed through simulation outputs, such as battery charging/discharging currents and system output currents, to evaluate the effectiveness of the fuzzy logic controller in power management.
