| 摘 要： | 变风量空调是一个多输入多输出的系统,由于具有多个回路,各个回路之间相互影响,具有强耦合、非线性和大时滞等特点.常规PID控制存在稳定性与精确性的矛盾.文中根据自抗扰控制原理,分析了变风量空调系统的耦合关系,通过扩张状态观测器实现对系统总扰动的估计和补偿,实现解耦控制.文中将其用于变风量空调末端的主回路温度控制系统.仿真实验结果表明,与PID控制相比,自抗扰控制器的超调量、时滞等得到了明显改善.

| Abstract: | Variable air volume air conditioning system （VAV） is a multiple input and multiple output system,because it has a lot of loop and each loop has an interaction with each other.It leads the system has strongly coupled,nonlinear,larger time delay and so on.The conventional PID control has the contradictions about stability and accuracy.This paper,based on ARDC control principle,analyses the air conditioning decoupling.It estimates the total system of disturbance and compensation through the ESO,and achieves the decoupling control.The main loop of the end of the variable air volume air conditioning temperature control system is presented.The simulation results show that,compared with PID control and ADRC controller enables overshoot,delay has been significantly improved. |
