基于模糊控制算法的纯电动汽车空调控制器的研发

Design of electric automobile air conditioning controller based on fuzzy control

摘要:

纯电动汽车迅速发展,要求其空调系统也急需跟进。根据纯电动汽车特点,开发出一种纯电动汽车空调控制器系统,设计了空调控制器的电源模块,阐述了使用无位置传感器控制压缩机无刷直流电机的原理,研发了一种过流检测电路。提出了一种新型控制方法,即：在考虑整车负载的基础上,使用多输入变量模糊控制算法对汽车空调压缩机电机进行控制,同时兼顾了乘员的舒适性与汽车的动力性。结果表明这种空调控制器运行良好,达到了预期效果。

Abstract:

The air conditioning system must follow up the rapid development of pure electric vehicles. According to the characteristics of electric vehicles, design an air conditioning controller system. Design the power supply module for air conditioning controller. Using of position sensors to control the brushless DC motor for compressor. Design an over-current detection circuit. To meet the needs of both the power and the comfort of the car, propose a new control method of controlling the automobile air conditioning compressor motor basing on multiple input variables of the fuzzy control algorithm, in the condition of load vehicle. Results show that this controller has good air conditioning operation.
