基于等效能量燃烧模式切换控制策略设计
Design of switching control strategy based on equivalent energy burning mode
在柴油机进行燃烧模式切换时,往往伴随着转速波动的问题。针对该问题,本研究在PID转速闭环控制策略基础上,基于等效能量原理建立了模式切换过程中主喷油量的修正模型,并搭建了GT-Power和Simulink联合仿真模型,设计了基于等效能量模型的燃烧模式切换策略。结果表明:试验中通过加入喷油量修正模型,柴油机在单次喷射模式向多次喷射模式切换的过程中,转速波动率从3.25%降至0.5%以内,相对降低了84.62%,且无明显的波动时长;多次喷射模式向单次喷…查看全部>>
During combustion mode transitions in diesel engines,there is often a problem of speed fluctuation.To address this issue,this research builds upon the PID speed closed-loop control strategy and establishes a modified model for the main fuel quantity during mode switching based on the equivalent energy principle.Additionally,a combined GT-Power and Simulink simulation model is constructed to design a combustion mode switching strategy using the equivalent ene…查看全部>>
