摘要

为了研究出一种高效的汽车空调控制逻辑系统

借助GT-SUITE仿真软件

建立了跨临界CO

空调动态仿真模型

以节流阀开度、压缩机转速、风机转速为被控参数

以排气压力、送风温度和车厢温度为目标参数

研究了多PID控制的启动顺序和启动延迟时长对系统动态响应性能的影响

并研究了环境温度和车速随时间变化的动态工况下系统的动态响应特性。结果表明:排气压力—送风温度—车厢温度的启动顺序可以提高动态响应性能

使排气压力和送风温度的稳定时间分别缩短75%和38.9%

节流阀开度、压缩机转速、风机转速的波动范围分别减小85%、50%和63.3%; 3个PID控制器依次延时40 s启动时压缩机和风机转速的波动范围相比其他延时控制分别下降50%和63.3%

即提升了控制系统的稳定性; 在环境温度和车速随时间发生变化的过程中

PID控制响应迅速

控制目标参数的实时值稳定性高。本文提出的控制方式高效稳定

可为实际空调工程的控制设计提供参考。

Abstract

A GT-SUITE simulation software is used to establish a transcritical CO

air conditioning dynamic simulation model and to find efficient control logic of automobile air conditioning. The opening of throttle

compressor speed and fan speed are taken as controlled parameter; the discharge pressure supply air temperature and cabin temperature are taken as target parameter. The influence of the startup sequence and delay time on the dynamic response performance is studied. In addition

the dynamic control response characteristics under variable ambient temperature and vehicle speeds are explored. Results and comparisons with other sequences show that

proper start sequence improves dynamic response performance

and the sequence with discharge pressure-supply air temperature-cabin temperature lead the stabili-ation times of the discharge pressure and the air temperature to be shortened by 75% and 38.9%

respectively; and the ranges of opening of throttle

compressor speed

fan spee
