Problems solved by technology

However, due to the time-varying, strong coupling and uncertain internal working parameters of the fuel cell system, coupled with the disturbance of external load and ambient temperature, it is difficult for the traditional PID control to achieve ideal results.
At the same time, PID control is based on error feedback control, that is, when the system is stable, there is a steady-state error between the system output and the control quantity

Abstract

The invention discloses application of a fuzzy proportion integration differentiation (PID) algorithm in a fuel cell radiating system. The fuel cell radiating system comprises a water tank connected with a fuel cell, wherein the water tank is connected with a radiator and a radiator fan through a circulating water pump and a corresponding pipeline; a main controller acquires a data signal of the fuel cell through a sensor and transmits the data signal to a fan controller; and the fan controller controls the rotating speed of the radiator fan, and obtains a corresponding rotating speed of the radiator fan through the fuzzy PID algorithm to realize corresponding radiating capacity. The application of the fuzzy PID algorithm combines fuzzy control and PID control and has the advantages of flexible fuzzy control, strong adaptability and high control accuracy.

Description

technical field [0001] The invention relates to the cooling technology of the fuel cell system, more specifically, the application of a fuzzy PID algorithm in the cooling system of the fuel cell. Background technique [0002] A fuel cell is a power generating device that converts chemical energy in fuel directly into electrical energy. The temperature control of the fuel cell system is an important link in the control of the fuel cell system, and its control effect has a great influence on the system output, system performance, and system life. In this paper, the fuel cell temperature control system is studied; fuzzy PID control and radial neural network PI control are proposed for the large inertia and large overshoot of the fuel cell cooling system. Using simulation analysis, the control effects of the two control methods are compared, and the radial Neural network PI control; after experiments, the results show that the temperature control using this algorithm has the ...
