在工业生产过程中，有效地控制换热器的换热性能会产生显著的经济效益和社会效益。采用LQ最优控制理论，给出了一种基于PLC的换热器控制系统设计方案。依据换热器控制系统给出系统控制模型，结合LQ最优控制理论求出控制器的目标函数，最后用仿真软件测试。结果表明，所提出的最优控制方法不但简单，而且能有效地解决换热器的控制问题。在某工厂的试运行中，换热器的有效性也得到了验证。

Heat exchanger is widely used in industrial and commercial fields as energy exchange equipment. Effective control of the heat exchanger can not only generate significant economic benefits,and can also produce significant social benefits. A LQ optimal controller for heat exchanger is proposed in this paper based on optimal control theory. The simulation results show that the proposed controller is effective. And experiment test also confirms this result.
