摘要
本文分析了变风量空调房间温度控制的控制策略,建立了房间的仿真模型,重点介绍了自抗扰控制技术的原理和算法。通过把其应用到温度控制回路中,与常规PID进行对比,仿真结果表明,在对变风量末端进行控制时,自抗扰控制方法能够有效克服房间对象中的不确定性和热扰动,使房间温度稳定在设定值周围,波动范围很小。
The temperature control strategies of VAV(variable air volume) air conditioning are discussed in the paper, and the room's simulation model was established by using Matlab/Simulink toolbox; the principle and algorithm of the active disturbance rejection control(ADRC) are introduced. The ADRC is applied to the temperature control circuit of VAV terminal. Compared with the conventional PID, the simulation results show that the ADRC can effectively overcome the uncertainty and thermal disturbance which is in the room, as well as make room temperature stable around the set value, the fluctuation range is very small.
