Research on energy-saving control of plug-in parallel hybrid tractor based on adaptive threshold optimization
Taking the plug-in parallel hybrid tractor as the research object,in order to maximize the advantages of electric energy in the process of operation,the idea of rolling optimization is adopted,and the energy-saving control strategy of hybrid tractor based on adaptive threshold optimization of time window is proposed.The drive system model of the plug-in parallel hybrid tractor is built,the switch strategy of the tractor's multiple energy modes is formulated,and the adaptive optimization of the key threshold parameters is studied.Based on the tractor ploughing condition,the simulation comparison between the strategy in this paper and the power following strategy is carried out using the Matlab/Simulink simulation platform.The results show that the equivalent fuel consumption of the energy-saving control strategy of the hybrid tractor based on the adaptive threshold optimization of the time window is reduced by 8.78%under the cycle plowing condition,which provides a new control method for the energy-saving control of the plug-in parallel hybrid tractor.
