摘要
采用机理分析和实验分析相结合的方法,建立了恒温恒湿空调系统的数学模型,推导了四输入、四输出的传递函数矩阵,并采用前馈补偿法设计解耦补偿器,使恒温恒湿空调系统的传递函数矩阵变换为对角矩阵,从而解除了各个控制回路之间的耦合.仿真结果表明,该解耦控制器在恒温恒湿空调系统中的应用效果较好,改善和提高了系统的品质和性能.
A mathematical model of constant-temperature and constant-humidity air-conditioning （CTHAC） system was developed by combining the theoretical analysis with the data analysis of experiment, and a transfer function matrix with four-input and four-output was derived. The decoupling compensator of CTHAC system was designed in the way of feed forward compensation, so that the transfer function matrix could be transformed into diagonal matrix and the coupling among the four control loops was eliminated. The simulation result showed that the decoupling controller exhibited better result of application in constant-temperature and constant-humidity air-conditioning system and improved the quality and performance of the system.
