摘要
为保持纯电动汽车车室环境的热舒适性并提高能量使用效率,本文对纯电动汽车热泵空调系统的控制策略进行了研究。利用AMESim搭建了纯电动汽车热泵空调系统车室仿真平台,设计了开关控制策略、PID控制策略和模糊控制策略。采用Matlab/Simulink分别对3种控制策略进行仿真。在模糊控制策略的基础上加入了前馈控制环节并进行仿真。结果表明:开关控制策略、PID控制策略和模糊控制策略下COP值分别约为1.50、1.80和1.85;引入前馈控制环节前温度波动约为0.5℃,引入后无明显变化。在系统的动态响应和能效比方面模糊控制策略的控制性能优于开关控制和PID控制;加入前馈控制环节后的模糊控制策略有效地提高了系统在外部环境变化时的系统动态响应,降低了车室温度的波动。
In order to maintain thermal comfort of the cabin environment of a pure electric vehicle and improve efficiency of energy use,this paper studies the control strategy of the heat pump air conditioning system for pure electric vehicles.AMESim is used to build a cabin simulation platform of the pure electric vehicle heat pump air conditioning system,and three control strategies are designed:compressor on/off control strategy,PID control strategy and fuzzy control strategy.Matlab/Simulink is used to simulate the three control strategies respectively,and then feedforward control is added and simulated on the basis of the fuzzy control strategy.The results show that the COP values under the compressor on/off control strategy,the PID control strategy and the fuzzy control strategy are about 1.5,1.8 and 1.85 respectively;the temperature fluctuation is about 0.5℃before the introduction of feedforward control,and there is no significant change after the introduction.The control performance of the fuzzy control strategy is better than that of the compressor on/off control and the PID control in terms of dynamic response and energy efficiency ratio of the system;after adding the feedforward control,the fuzzy control strategy effectively improves the dynamic response of the system when the external environment changes,and reduces the fluctuation of the cabin temperature.
