变风量空调的自适应解耦控制研究
Research on adaptive decoupling control in variable air volume air conditioning system
摘要
Abstract
The variable air volume air-conditioning is a multiple input multiple output coupling system, and because the actual system is influenced by many factors, the system model parameters are also changed. According to the system of the coupling and changeable, this paper puts forward a kind of online identification based on adaptive decoupling control strategy which is used in the variable air volume air-conditioning system. This control strategy uses a recursive forgetting factor and parameter identification algorithm based on model matching of zero frequency. When system is operating in closed-loop control conditions, process parameters are identified online. Based on the model to design the controller and the decoupling device, and the relative control loop is decoupled. To the actual system, two coupled loop is simulated and experimented. The results show that this method is effective to improve the coupling effect of the system, improve the stability and robustness of the control system.关键词
