Description
Technical Field
The invention relates to the technical field of fuel cell boosting DCDC control, in particular to a vehicle-mounted fuel cell boosting DCDC control method and system.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The fuel cell bus is a novel energy bus, and is an 'electric and electric' hybrid system formed by combining a fuel cell and an auxiliary power cell in a strict sense. Since the output voltage of the fuel cell is insufficient to meet the voltage required by the high voltage distribution box, a boost DCDC converter needs to be added between the fuel cell and the high voltage distribution box to boost the voltage to the voltage required by the high voltage circuit and the load. The boost DCDC plays a role in the conversion of the fuel cell in terms of high and low voltages.
However, the inventors have found that in the vehicle-mounted fuel cell boost DCDC control technique, with frequent start-up of the fuel cell engine (FCU), DCDC will also follow the loading and unloading of the fuel cell engine to effect a change in operating mode. The time for the DCDC to enter or exit the working mode is determined by the load-reducing speed and the target set current value sent by the FCU, the time for the load-reducing speed to reach the target set current value is longer when the load-reducing speed is slow, the current is unstable in the speed-increasing process when the load-reducing speed is too fast, and balance between the load-reducing speed and the target set current value is required to be maintained, so that the high-efficiency and stable work of the boosting DCDC of the fuel cell system under the dynamic load-reducing is ensured, and the service life of the fuel cell is prolonged.

The fuel cell enters a starting or closing state according to the enabling signal, and then the system is judged to enter a loading or unloading mode;
The DCDC adjusts the current to a target current value according to a set load rate or unload rate.
Further, if the system enters a loading mode, the DCDC receives a starting command of the FCU, and the DCDC rises to a target current value at a set loading rate.
Further, if the system enters the load shedding mode, the DCDC receives a shutdown command of the FCU, and simultaneously the DCDC reduces to a target current value at a set load shedding rate.
Further, the FCU receives a start-up or shut-down signal of the whole vehicle controller, and further controls the DCDC.
Further, when the vehicle controller needs the FCU to generate power, a signal for starting the FCU is sent, and after the FCU has a load pulling condition, the DCDC is controlled to pull the load at a set loading rate.
Further, when the FCU does not need to generate power, the VCU sends a signal for shutting down the FCU, and after the FCU has a load shedding condition, the DCDC is controlled to perform load shedding at a set load shedding rate.
Further, the DCDC is started or shut down according to the condition that the load-up setting target current is larger than the output current of the fuel cell, and the DCDC is started in a loading way; and when the load reduction set target current is smaller than the output current of the fuel cell, the DCDC performs load reduction shutdown.
Further, the loading rate is obtained by an integral-split PID control algorithm.
Further, in the integral separation type PID control algorithm, when the deviation between the output current of the fuel cell and the DCDC load-lifting set target current is smaller than a threshold value, integral control is introduced, and PID control is adopted;
When the deviation between the output current of the fuel cell and the DCDC load-up setting target current is larger than a threshold value, the integral control is canceled, and the PD control is adopted.
Further, the load shedding rate is obtained by an integral separation type PID control algorithm.

Δu(k)＝Itarget(k)-Ioutput(k) (1)
Δu(k-1)＝Itarget(k-1)-Ioutput(k-1) (2)
