VAV空调系统末端解耦控制研究

通过对VAV变风量空调系统的两个末端控制回路之间的耦合进行分析,运用最小二乘法建立被控对象＂送风量—室内温度＂控制回路的数学模型。针对被控对象的特性,采用前馈补偿解耦方法设计解耦网络,并设计单神经元自适应PID控制器。最后,通过MATLAB仿真,证明了所设计的解耦网络和控制器是行之有效的。

The study on the terminal decoupling control of VAV system

Using least squares method,a mathematical model for air value-indoor temperature loop was established.In addition,adaptive PID Controller of A Neural Network and feedforward compensation decoupling network have been designed to eliminate the coupling between two loops.The feasibility and validity of the controller and the network is testified by simulation.
