(the i under discharge mode of device 2sc0) One Buck-Boost converter body shows as Boost to >, (the i under charge modesc< is 0)
One Buck-Boost converter body shows as Buck converters.As the control targe of One Buck-Boost converter body is to ensure iucMoment with
Track its reference value iuc-ref, we can be defined shown in a binary variable k such as formula (3):
As k=1, S3Gate drive signals u3It is set to 0, S2Gate drive signals u2For pwm signal, it is contemplated that u2Enter for two
System (0,1) between the numerical value that changes, following bilinearity switch models are obtained:

As k=2, S2Gate drive signals u2It is set to 0, S3Gate drive signals u3For pwm signal, it also is contemplated that to u3For
Binary system (0,1) between the numerical value that changes, then bilinearity switch models be changed into:
i2=u3iucFormula (7)
On the basis of local module modeling, it is necessary to set up global system model to obtain the optimum control of control targe
System.The world model of One Buck-Boost converter body can be obtained from formula (4)-(7):
i2=[k (1-u2)+(1-k)u3]iucFormula (9)
On the other hand, can obtain from Fig. 2 and formula (9):

Also it is u1And u23Mean value.
Control strategy it is good with it is bad, often by control targe evaluating.Its control targe design of control strategy is as follows:
(1) in the case where load is continually changing, stable DC busbar voltage vdc.DC bus-bar voltage is more stable, is combined
Power supply energy and power conversion efficiency are higher;
(2)iucMoment tracks its reference value iuc-ref.The instantaneous power that ultracapacitor is mainly undertaken in bearing power is needed
Ask, by active control iucMoment tracks its reference value iuc-ref, it is ensured that ultracapacitor carries out power benefit to battery in time
Repay, iuc-refIt is embodied in the situation of change of load current;
(3) control system realizes asymptotically stable in the large.
1) non-linear control strategy design
First control targe is to ensure that DC bus-bar voltage vdcTrack its constant reference value vdc-ref, but total institute's week
Know, Boost has non-minimum phase feature.For this problem, not to vdcAnd vdc-refDirectly controlled, but
Using control inductance L1Input current ibfThis method for indirectly controlling is solving.Definitely show as:Inductance L1Input current
ibfTrack its reference current value ibf-ref, during systematic steady state, have ibf=ibf-ref, vdc=vdc-ref, vdc-ref> vb.From the conservation of energy
Angle considers that input power is equal to power output, therefore ibf-refWith vdc-refRelation it is as follows:
Wherein, λ >=1, is fissipation factor, including switching loss and inductor loss.
In order to realize first control targe, we introduce error variance such as formula (19), e here1Value is less, and direct current is female
Line voltage is more stable.e1Mean value can be derived from from formula (15), be specifically shown in formula (20).
e1=x1-ibf-refFormula (19)
E to be allowed1Value is less, namelyValue is less,Execution can behave as:
Wherein, c1> 0 is defined as design parameter, e3For DC bus-bar voltage vdcMean value x3With its design load x3dBetween
Error, see formula (22), x3dExpression formula can specifically give hereinafter.
e3=x3-x3dFormula (22)
With reference to formula (20), (21), the control rule of Boost input signal is obtained:
Wherein, e3For the damping term in control rule, its effect is adjustment output response.
Next step, is to realize second control targe, need to formulate One Buck-Boost converter body input signal μ23Control rule
Then.For this purpose, introducing error variance e2:
e2=x2-iuc-refFormula (24)
According to formula (16), mean valueFor:
Equally, realize iucMoment tracks its reference value iuc-ref,Value it is the smaller the better,Execution can behave as:
Wherein, c2> 0 is also design parameter.
With reference to formula (24) and (26), input signal μ23Control rule it is as follows:
So far, the first two control targe is finished with designing, and whether next step checking closed-loop control system is stable.
2) stability analysis
3rd control targe is that composite supply control system realizes asymptotically stable in the large, can from formula (23) and (25)
Hand, by state variable (e1, e2, e3) judging, set up shown in secondary liapunov function such as formula (28):
Purpose causes the mean value of VNegative definite,Can obtain from formula (21), (26) and (28):
Wherein, c3> 0 is still design parameter.
Therefore, secondary liapunov function is rewritable in this case is:
Can be seen that from formula (31)Containing state vector (e1, e2, e3) closed-loop system asymptotically stable in the large.
Finally, it is available from formula (17), (22) and (30):
