摘要

Under the condition of low temperature, the heat pump air conditioning system of electric vehicle has obvious time-varying and hysteresis.This paper proposes a heat pump air-conditioning control strategy based on the combination of PID control and fuzzy control, which integrates the advantages of PID control and fuzzy control and is used for the electric vehicle heat pump air-conditioning system to solve the problem of insufficient temperature stability in the vehicle under low temperature condition.The experiment shows that under the condition of maintaining overmodulation and steady-state error, the pid-fuzzy compound control strategy has an improvement in reducing the regulation time compared with the traditional control strategy, which is 29.5% lower than PID control and 6.1% lower than fuzzy control.
