Research on control strategy of hybrid electric vehicle air conditioning based on disturbance feedforward compensation

The air conditioning system of a hybrid vehicle has an important impact on the comfort and energy utilization of the vehicle. Based on AMESim platform and Simulink software, this paper builds a simulation model of the air conditioning system and passenger compartment of a hybrid vehicle, and investigates the effects of three different control strategies such as PID control, fuzzy control, and fuzzy control with the introduction of feed-forward link on the temperature drop in the passenger compartment and the energy efficiency of the whole vehicle. The results show that the fuzzy control with feed-forward link has the shortest temperature drop response time and strong stability, and the vehicle energy efficiency ratio (COP) under PID control, fuzzy control, and fuzzy control with feed-forward link are 1.79, 1.83, and 1.86, respectively, which indicates that the fuzzy control with feed-forward link improves the energy utilization efficiency effectively.
