电动汽车中的空调系统必须完成多重任务，即确保乘客的热舒适性和调节电池。本文提出了四种基于模型的空调系统控制方法。比较了这两种方法跟踪期望参考值、抑制干扰和避免饱和效应的能力。
两种方法是反馈控制器、分散比例积分控制策略和集中线性二次积分控制策略。另外两种方法在两自由度控制结构中将反馈控制器与基于逆的前馈控制器相结合。此外，这四个概念由汉努斯条件抗饱和机制补充。
所提出的四个控制器中的三个明确地考虑了多输入多输出系统的耦合，这允许高性能的控制。此外，所有方法都具有基于受控系统的物理模型的优点。该物理模型的开发和识别是论文的一部分。
控制器的物理基础确保了高水平的可重用性，从而确保了高效的控制器设计过程。提出的控制概念通过测试平台的测量数据进行验证和比较。
通俗来讲，就是专门用户控制工业控制中的计算机，在智能控制中是核心的部件，可以在其内部执行逻辑运算、顺序控制等指令，可以对工业控制领域的各种类型的设备或者生产线进行控制，目前，机床、包装机械以及汽车行业是PLC主要的三大市场。

The air conditioning system in electric vehicles must accomplish multiple tasks, namely, ensuring the thermal comfort of passengers and adjusting batteries. In this paper, four control methods of air conditioning system based on model are proposed. The ability of these two methods to track the expected reference value, suppress interference and avoid saturation effect is compared.
The two methods are feedback controller, decentralized proportional integral control strategy and centralized linear quadratic integral control strategy. The other two methods combine feedback controller with feedforward controller based on inverse in two-degree-of-freedom control structure. In addition, these four concepts are supplemented by Hannus's conditional anti-saturation mechanism.
Three of the proposed four controllers explicitly consider the coupling of multi-input and multi-output systems, which allows high-performance control. In addition, all methods have advantages based on the physical model of the controlled system. The development and identification of the physical model is a part of the paper.
The physical foundation of the controller ensures a high level of reusability, thus ensuring an efficient controller design process. The proposed control concept is verified and compared by the measurement data of the test platform.
Generally speaking, it is the computer controlled by special users in industrial control, which is the core component in intelligent control. It can execute instructions such as logical operation and sequence control in it, and can control various types of equipment or production lines in industrial control field. At present, machine tools, packaging machinery and automobile industry are the three main markets of PLC.
