Simscape 中的燃料电池汽车模型.zip

%% Vehicle with Fuel Cell Powertrain % % This example shows a fuel cell powertrain modeled in Simscape. A single % fuel cell stack in parallel with a battery powers a single motor that % propels the vehicle. The fuel cell is modeled using a custom domain to % track the different species of gas that are used in the fuel cell. The % vehicle can be tested on custom drive cycles or using the Drive Cycle % Source from Powertrain Blockset. % % Products Used % % * <https://www.mathworks.com/products/matlab.html MATLAB> % * <https://www.mathworks.com/products/matlab.html Simulink> % * <https://www.mathworks.com/products/simscape.html Simscape> % * <https://www.mathworks.com/products/simscape-driveline.html Simscape Driveline> % * <https://www.mathworks.com/products/simscape-electrical.html Simscape Electrical> % * <https://www.mathworks.com/products/simscape-fluids.html Simscape Fluids> % * <https://www.mathworks.com/products/powertrain.html Powertrain Blockset> % % % Copyright 2019-2023 The MathWorks, Inc. %% Model open_system('ssc_car_fuel_cell_1motor') set_param(find_system(bdroot,'MatchFilter',@Simulink.match.allVariants,'FindAll','on','type','annotation','Tag','ModelFeatures'),'Interpreter','off'); %% Powertrain Subsystem % % The fuel cell and battery are connected on a DC electrical network to the % motor. The control system determines how much power to draw from the % battery and fuel cell. During braking events, power is fed back into the % battery to recharge it. A thermal system modeled using a fluid network % controls the temperature of the battery, DC-DC converters, and the motor. open_system('ssc_car_fuel_cell_1motor/Vehicle/Powertrain/FuelCell1Motor','force') %% Fuel Cell Subsystem % % The flow of oxygen, hydrogen, nitrogen, and water is captured in a custom % Simscape domain.
