摘要
本文分析了空调控制系统、变风量空调系统特点及目前存在的控制问题,提出了空调控制系统引入智能控制方案的可行性与必要性,针对变风量空调系统的特点和要求,提出变风量空调系统的控制方案。控制回路由冷水流量—送风温度控制、风机转速—静压点静压控制、送风量—室内温度控制、新风量—二氧化碳浓度控制四个控制回路组成,建立了一种新的多层神经网络,实现了神经网络和PID控制规律的本质结合,在变风量空调控制系统中表现出很强的学习和自适应解耦能力,MATLAB仿真试验说明了系统设计的有效性。
This thesis analyes air-condition control system, the characteristics of variable air-volume air-con- dition system and actual control problems. It brings forward the feasibility and necessity of intelligent control in the air-condition system, and brings forward the air-condition control system, according to the character and request of variable air-volume air-condition. The control loop is composed of water flux-air temperature control loop, trans- ducer-electromotor pressure control loop, air volume-room temperature control loop and fresh air valve-CO vol- ume control loop. The result of MATLAB simulation shows the validity of the system design.
