The invention discloses a kind of proton exchange film fuel battery system temperature Active Fault-tolerant Control Methods.Initially set up the model of PEMFC Temperature control system, model foundation system structure matrix is directed to by structured analysis method, and use Dulmage-Mendelsohn decomposing system structure matrix, obtain model redundancy section, and difference is constructed more than system to reflect temperature control system sensor fault, on the basis of fault identification, the active tolerant control based on sliding formwork is devised, accurate control is realized to pile outlet temperature.The present invention solves the problems, such as the sensor failure of proton exchange film fuel battery system Temperature Control Model in the process of running, and the faults-tolerant control based on model is applied in temperature control, can effectively improve the reliability and durability of fuel cell system. |
