Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with the technology of the present invention side
Implement premised on case, give detailed embodiment and concrete operating process, but the protection model of the present invention
Enclose and be not limited to following embodiment.
Embodiment 1
The present embodiment provides a kind of anode of fuel cell pressure control device, as it is shown in figure 1, include PID control
Device 1, spray rail 2, relief valve 3, fuel cell pack 4 (FC Stack) and anode of fuel cell pressure transducer (figure
Not shown in), fuel cell pack 4, anode of fuel cell pressure transducer, PID controller 1, spray rail 2, let out
Pressure valve 3, fuel cell pack 4 are sequentially connected with, and form closed loop controlling structure, are provided with multiple nozzle in spray rail 2.Combustion
The anode of fuel cell pressure P that material galvanic anode pressure transducer feedback is actualanode(PanodeFor entering the hydrogen of pile
Pressure).As desired anode of fuel cell pressure PsetWith currently practical anode pressure P fed backanodeHave partially
During difference Δ P, PID controller deviation signal is calculated controlled quentity controlled variable d, obtains after integer (rounding up)
To controlling to spray unlatching number n of rail nozzle, and then control spray rail and after relief valve adjusts, obtain desired fuel electricity
Pond anode pressure.
As in figure 2 it is shown, the present embodiment also provides for a kind of anode of fuel cell compress control method, comprise the following steps:
1) anode of fuel cell pressure transducer gathers real-time anode pressure P of fuel cell packanode(PanodeAlso
For entering the Hydrogen Vapor Pressure of pile).
2) PID controller is according to controlled quentity controlled variable d of expectation anode pressure employing PID closed loop control acquisition correspondence:
Wherein, d is controlled quentity controlled variable, kp、ki、kdBe respectively the proportionality coefficient of PID closed loop control, integral coefficient and
Differential coefficient, Δ P is the deviation signal of real-time anode pressure and expectation anode pressure.
It is that the amount controlling spray rail nozzle unlatching number (is not necessarily whole by the calculated controlled quentity controlled variable of PID controller
Number).
3) opening of each nozzle in spray rail is controlled according to controlled quentity controlled variable, particularly as follows:
31) described controlled quentity controlled variable d carries out integer (rounding up, Round ()) process, be converted into spray rail
Unlatching number n of middle nozzle；
32) all nozzles in spray rail being numbered, according to step 31) unlatching number n that obtains is by configuration scheduling
Strategy obtains the numbering of the nozzle that needs are turned on and off；
33) control respective nozzle to be turned on and off.
4) relief valve judges that the Hydrogen Vapor Pressure spraying rail output whether more than setting pressure, the most then opens relief valve
Until Hydrogen Vapor Pressure drops to set pressure, it is ensured that in pipeline and fuel cell pack, Hydrogen Vapor Pressure is in rated range, keeps away
Exempt from pipeline or damage of facilities and accident occurs, and Hydrogen Vapor Pressure fluctuation can come via the adjustment of relief valve opening and closing speed
Eliminate, keep the anode of fuel cell pressure of safety and stability.
5) the hydrogen input fuel cell pack after Stress control.
In the present embodiment, configuration scheduling strategy is the scheduling using circulationization principle to carry out each nozzle, particularly as follows:
In each control cycle, record the total degree that all nozzles are opened, obtain the spray being turned on and off according to complementation
Mouth is numbered, and is i.e. realized the round-robin scheduling of nozzle by the numbering of circulation.
As it is shown on figure 3, set spray rail have N number of bore same nozzle, each nozzle has open and close two states,
Successively numbered to each nozzle 1,2 ... N-1,0.As a example by 4 nozzles, successively each nozzle is entered
Line number, respectively 1,2,3,0.
Being located in the control cycle, the total degree that all nozzles are opened is S.Time initial, S=0, and later
Constantly it is cumulatively added, i.e. whenever needing a new nozzle and opening, S=S+1.Set K as needing the spray opened
Mouth is numbered, and makes K=S%N, and carrying out complementation, even remainder is 0, i.e. K=0, then No. 0 nozzle is opened,
By that analogy, the nozzle of numbered N-1 is opened during K=N-1；To the non-nozzle opening numbering, then need to close.
If opening u nozzle, then having N-u nozzle to need to close, from the beginning of numbering K+1, numbering is incremented by one by one,
To being recycled to numbering 0 during N-1 again, then it is incremented by one by one, until N-u the nozzle that be there is a need to close is whole
Close.Similar to opening Nozzle methods, if G is the nozzle numbering needing to close, takes H=S, make H=H+1,
G=H%N, carrying out complementation, even remainder is 0, i.e. G=0, then No. 0 nozzle is closed, and closes during G=N-1
The nozzle closing numbered N-1 is closed.
Embodiment 2
The present embodiment is with the difference of embodiment 1, and in the present embodiment, configuration scheduling strategy is for using random assortment former
Then carry out the scheduling of nozzle, particularly as follows: within each control cycle, randomly select requisite number according to opening number n
The nozzle of amount is opened, and remaining nozzle is closed, and chooses every time and all takes out at random in the residue not comprising the number of a collection of selected materials is numbered
Take.
As shown in Figure 4, setting spray rail has N number of bore same nozzle, and each nozzle has open and close two states,
Successively numbered to each nozzle 0,1,2 ... N-1.As a example by 4 nozzles, successively each nozzle is entered
Line number, respectively 0,1,2,3.
Within a control cycle, randomly select the nozzle numbering of requirement.1st numbering is 0 to N-1
Scope in choose, the 2nd in addition to the 1st numbering chosen remaining numbering in take, the most every time not
The residue numbering comprising the number of a collection of selected materials is randomly drawed.If desired open u nozzle, then randomly select u numbering,
Open correspondence and choose the nozzle of numbering.Under described algorithm, the selected probability of each numbering is equal, is all
The invoked chance of the most each nozzle is impartial and random.Nozzle is achieved by nozzle numbering is randomly selected
Balance call.
Therefore, the scheduling strategy opening nozzle numbering in real time of the spray rail in the present invention can make each nozzle be balanced
Utilize, it is to avoid single nozzle is overheated because excessively using or frequently using to be burnt, and improves each nozzle operation situation, prolongs
Its service life long, thus improve the pressure controlled reliability of anode of fuel cell.
In the case of without departing substantially from this patent essence, can will do corresponding change or as required on Control system architecture
Increase corresponding sensor, but these corresponding variations all should belong to the claims belonging to this patent it
In.
