Abstract

The invention discloses a PID control method of a fuel cell system. The PID control method comprises: constructing a theoretical database of a fuel cell, the theoretical database comprising power parameters and cooling liquid temperature parameters, hydrogen flow parameters and air flow parameters corresponding to the power parameters; obtaining a theoretical parameter value of the fuel cell and an actual parameter value corresponding to the theoretical parameter value, and calculating a deviation value between the actual parameter value and the theoretical parameter value, the theoretical parameter value being any one of a cooling liquid temperature value, a hydrogen flow value and an air flow value; inputting the deviation value into a preset PID control algorithm to calculate the control quantity of the fuel cell; and controlling a corresponding execution mechanism to adjust the temperature, the hydrogen flow or the air flow of the cooling liquid input into the fuel cell according to the control quantity, wherein the execution mechanism is a cooling system, a hydrogen supply system or a gas supply system. The invention is beneficial to improving the control precision of controlling the operation of the fuel cell system and improving the response speed of controlling the fuel cell system.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a PID control method for a fuel cell system. Background technique [0002] As we all know, hydrogen fuel cell is a clean energy fueled by hydrogen, and hydrogen fuel cell is also one of the development directions of clean energy in the future. [0003] The existing hydrogen fuel cell operation mode generally adopts PID (Proportion Integration Differentiation) controller, which controls the fuel cell system by calibrating parameters, and then corrects it through an algorithm near the target value, resulting in the traditional PID controller running In the process, there will be problems of slow response speed and large error. Contents of the invention [0004] The main purpose of the present invention is to provide a PID control method for a fuel cell system, aiming at solving the technical problems of slow response speed and large error in existing PID controllers.
