Title Fuel cell temperature modeling and fractional order PID controller design
Abstract Now the whole world faced with the shortage of energy and environmental pollution problems, the fuel cell as a power device, a new, energy shortage and environmental pollution solution provides a new scheme, which in the field of electric power energy is revolutionary。 Among them, proton exchange membrane fuel cell (PEMFC) has the advantages of high power density, fast response, less environmental pollution, etc。, and has broad application prospects。 So the modeling and control of the proton exchange membrane fuel cell is very important, which is helpful to the safe operation of the fuel cell, the improvement of the power generation efficiency, the prediction and analysis of the system performance。
Therefore, the main research of this paper is the fuel cell temperature modeling and the fuel cell temperature control based on fractional order PID controller:
(1)Introduced the working principle of the proton exchange membrane fuel cell and its performance and characteristics, and its influence factors into the fuel cell
The effect of temperature on the fuel cell was studied。
(2)According to the characteristics of the temperature of the proton exchange membrane fuel cell, the temperature characteristic model is established, and the temperature characteristic of the fuel cell is MATLAB。
Building simulation model with Simulink
(3)The principle of the PID controller is introduced, the design of fractional PID controller, PID controller parameters
The temperature characteristic of the proton exchange membrane fuel cell was observed under the PID controller, and the difference between the integer order PID and the fractional order PID controller was compared。 The simulation results show that the fractional order PID controller has better control effect than the integer order PID controller, and its overshoot is significantly smaller than the integer order PID controller。
Keywords PEMFC ，the integer order PID controller ，temperature，model
