Description
Technical field
The present invention relates to field of fuel cell technology, and in particular to a kind of fuel cell system air supply Internal Model Decoupling control
Device processed.
Background technique
Fuel cell car have the advantages that it is quiet, efficiently, not available for the orthodox cars such as zero-emission (environmentally protective), because
And the attention that relevant research, exploitation have been looked forward to by many countries, the world and vehicle.Compared to low-pressure fuel cell system, high pressure proton
Exchange film fuel battery (abbreviation high pressure fuel battery) system not only can further lifting system efficiency, system can also be increased
Power density reduces system dimension and improves the advantages such as water balance, this has highly important meaning in limited vehicle-mounted space
Justice.High pressure fuel battery system is the trend for being at present also the following vehicle fuel battery development.Such as Toyota (TOYOTA), Honda
(HONDA) and the companies such as Ba Lade (BALLARD) all use high pressure fuel battery as fuel cell system for vehicles.High pressure fuel
The air supply of battery system is different from the most important of low-pressure system blower air supply and is significantly a bit: the system is
Defeated one multi output coupled system of people more than one, but also have the characteristics that stronger non-linear, uncertain.It is changeable as one
Amount control system, the pressure and flow of the air supply of high pressure fuel battery system need optimised coordinated control, thus make be
System is whole to obtain good static and dynamic performance.
Currently, the synergic adjustment robust control of the air mass flow for high pressure fuel battery system and admission pressure both at home and abroad
Device design studies are also rarely reported.When system work in a wide range of or environment temperature and pressure (such as under altitude environment)
When varying widely, with master mould larger mismatch will occur for system model, and the control performance of system can also occur not at this time
With the decline of degree.
Summary of the invention
It is an object of the invention to solve above-mentioned technical problem, the control of fuel cell system air supply Internal Model Decoupling is provided
Device, not only realizes the decoupling of controlled volume, but also can obtain in the case where system model mismatch than traditional PI D decoupling controller
Better robustness, while controller parameter is few, adjusting is simple.
In order to solve the above technical problems, present invention employs fuel cell system air supply Internal Model Decoupling controller, packet
Air compressor machine, intercooler, gas gas humidifier, pile, counterbalance valve and connecting line are included, the air compressor machine is connect with the intercooler,
The intercooler is connect with the gas gas humidifier, and the gas gas humidifier is connect with the counterbalance valve, the controller control
The counterbalance valve and the air compressor machine are made, the controller receives the detection information for the sensor being set on the connecting line.
Further, in above-mentioned technical proposal, the air compressor machine is connect by connecting line with the intercooler, it is described in
Cooler is connect by connecting line with the gas gas humidifier.
Further, in above-mentioned technical proposal, the gas gas humidifier connects fuel cell.
The utility model has the advantages that this system is hollow for the air supply system of Proton Exchange Membrane Fuel Cells possessed by of the invention
Throughput and admission pressure control existing coupling problem, using Internal Model Decoupling control strategy progress controller design, and with
PID decoupling is compared.This controller can realize the decoupling of flow and admission pressure well, and in system model mismatch
In the case where can obtain robustness more better than traditional PI D decoupling controller.In addition, can by suitably adjusting filter parameter
With the dynamic property and robustness of easily and intuitively balance control system to meet actual needs.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention will be further described below with reference to the drawings.
As shown in Figure 1, the present invention provide fuel cell system air supply Internal Model Decoupling controller, including air compressor machine, in
Cooler, gas gas humidifier, pile, counterbalance valve and connecting line, air compressor machine are connect with intercooler, intercooler and gas gas humidifier
Connection, gas gas humidifier are connect with counterbalance valve, and controller controls counterbalance valve and air compressor machine, and controller, which receives, is set to connecting line
On sensor detection information.
Air compressor machine is connect by connecting line with intercooler, and intercooler is connect by connecting line with gas gas humidifier.
Gas gas humidifier connects fuel cell.
This system is deposited for air mass flow in the air supply system of Proton Exchange Membrane Fuel Cells and admission pressure control
Coupling problem, using Internal Model Decoupling control strategy carry out controller design, and with PID decoupling be compared.This control
Device can realize the decoupling of flow and admission pressure well, and can obtain in the case where system model mismatch than tradition
The better robustness of PID decoupling controller.In addition, can be convenient intuitively Balance route system by suitably adjusting filter parameter
The dynamic property and robustness of system are to meet actual needs.
The description and the appended drawings of the invention be considered as it is illustrative and not restrictive, on the basis of the present invention, ability
