The invention discloses a fuel cell hybrid power system multi-dimensional hysteresis control energy management method, and the method comprises the steps: introducing hysteresis control to each dimension of multi-dimensional input on the basis of an existing regular energy management control method: dividing the input condition of each dimension into a hysteresis interval and a non-hysteresis interval, equivalently, a hysteresis interval is used for replacing a previous interval demarcation point (or the hysteresis interval is inserted at the interval demarcation point), control is still carried out in a non-hysteresis interval according to the prior art, and target power control of the fuel cell is carried out in the hysteresis interval according to a hysteresis interval rule. Hysteresis control is introduced into each dimension of a multi-dimensional input rule type energy management strategy, the problem that the target output power of the fuel cell is frequently changed due to the fact that multi-dimensional input conditions frequently fluctuate up and down at interval demarcation points due to data acquisition, complex working conditions and the like is solved, the service life of a fuel cell system is prolonged, and the stability of the fuel cell system is improved.
本发明公开一种燃料电池混合动力系统多维度滞环控制能量管理方法,本发明在现有规则型能量管理控制方法的基础上,对多维度输入的每个维度均引入滞环控制:对每个维度的输入条件均划分滞环区间和非滞环区间,相当于用滞环区间来代替之前的区间分界点(或者说在区间分界点处插入滞环区间),在非滞环区间内仍按照现有技术进行控制,在滞环区间内将按照滞环区间规则进行燃料电池目标功率控制。本发明对多维度输入的规则型能量管理策略的每个维度均引入滞环控制,解决多维度输入条件因数据采集、复杂工况等原因在区间分界点频繁上下波动引起的燃料电池目标输出功率频繁变化的问题,提高燃料电池系统的寿命及稳定性。
