基于PIC的汽车空调控制器的设计

对于汽车空调这类强非线性系统,普通线性控制策略难以满足对控制效果的要求,智能控制策略更适合控制这类系统。简要介绍模糊控制原理,对其在汽车空调混合风门的控制进行详细介绍,结果表明具有较高的控制精度,分别从硬件及软件设计两个方面进行了阐述,对控制系统的控制单元进行了设计,采用PIC单片机作为控制单元处理器,对控制规则进行了设计。系统具有可靠性高、抗干扰能力强、电路简单等特性。

Development of automotive air conditioning controller DEMO based on PIC microcontroller unit

Linear control method is not suitable for controlling the non-linear system such as car air-conditioning system, while intelligent control method such as the fuzzy control method will control the system finely. The Fuzzy control theory is introduced simplily. And the use of it on the control of automotive air conditioning airmixing damper is introduced in details, the method has higher precision, also discuss the design from not only hardware but also software, control unit of control system is designed and taking PIC singleehip as processor,and the fuzzy logic rules is designed. The system has excellent characteristics, such as the high reliability, the strong antijamming ability, the simple circuit and so on.
