Embodiment Construction

[0075] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0076] In order to solve the control problem of the hydrogen fuel cell vehicle power system, the present invention proposes a whole process modeling method of the hydrogen fuel cell power system based on the improved fuzzy PID. Adjust the output power of the hydrogen fuel cell and the power battery in the power system of the hydrogen fuel cell vehicle, realize the rapid response of the power system of the hydrogen fuel cell vehicle to the speed change, and reduce the fluctuation of the output power of the hydrogen fuel cell.

[0077] The present invention starts with multiple factors such as the speed deviation, power deviation, and power distribution of fuel cell power cells of the hydrogen fuel cell vehicle power system, and designs a power system model eccentric fuzzy rule module, an acceleration braking module and a power distribution module...

Abstract

The invention discloses an improved fuzzy PID (Proportion Integration Differentiation)-based whole-process modeling method for a hydrogen fuel cell power system. Through cooperation of the eccentric fuzzy self-adaptive PID module, the acceleration braking module and the power distribution module, on the basis of ensuring the power output performance of the power system, fine control over the output characteristics of the hydrogen fuel cell automobile power system is achieved, the more complex variable load requirement of the hydrogen fuel cell automobile power system is met, on the premise of the same or better speed control effect, the large variable load time of the hydrogen fuel cell is greatly shortened, the service life of the hydrogen fuel cell is prolonged, meanwhile, more accurate acceleration brake control is achieved, and the control effect has higher robustness.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and proposes a method for modeling the whole process of a hydrogen fuel cell power system based on an improved fuzzy PID. Background technique [0002] In the field of new energy vehicles, the main development directions that can replace traditional fuel vehicles are pure electric vehicles and hydrogen fuel cell vehicles. At present, the relevant supporting technologies of pure electric vehicles are relatively mature, but the electric energy of pure electric vehicles is completely dependent on the power grid supply, so the degree of environmental protection depends on the environmental protection of the power generation method. At present, my country still uses traditional thermal power generation as the main source of pollution. In addition, due to the constraints of lithium battery technology, the development of pure electric vehicles is facing a bottleneck; hydrogen fuel cells have high energ...
