Abstract

The invention discloses a modeling system of a proton exchange membrane fuel cell (PEMFC) and an intelligent predictive control method thereof. The modeling system at least comprises an input-output nonlinear function structuring and implementing module and an intelligent predicative control module, wherein the input-output nonlinear function structuring and implementing module is used for structuring an input-output nonlinear function relationship and identifying the function by using a least square support vector machine method; and the intelligent predicative control module is used for carrying out nonlinear rolling optimization on a predicated target function by using a particle swarm optimization algorithm to acquire the optimal controlled quantity so as to realize the intelligent predicative control over the PEMFC. According to the invention, by means of establishing an output power characteristic model of a PEMFC stack by using input-output data, a complex reaction mechanism inside the PEMFC stack is avoided, and the modeling speed and the modeling precision are high.

Description

technical field

[0001] The invention relates to a proton exchange membrane fuel cell modeling system and its predictive control method, in particular to an identification model-based proton exchange membrane fuel cell modeling system and its intelligent predictive control method. Background technique

[0002] A fuel cell is a clean and efficient distributed power source that converts the chemical energy of hydrogen-containing fuel directly into electrical energy without a combustion process under the action of a catalyst. Proton exchange membrane fuel cell (protonexchange membrane fuel cell, PEMFC), as the most likely commercial fuel cell, has the advantages of low operating temperature, high current density, and fast response, and has broad application prospects. The operation process of PEMFC is relatively complicated. Its working principle involves fluid dynamics, thermodynamics, mass transfer, electrochemistry, materials science, process control and other disciplines. It...
