摘　　要：针对具有高阶大惯性特征的再热汽温过程(RSTP),提出了一种自适应抗扰控制方案和设计方法,实现了在不同负载下RSTP的抗扰控制。基于RSTP的运行机制和控制结构,分析了负荷波动引起的不确定性和相对增益变化。并在自抗扰控制(ADRC)框架中设计了控制增益的自适应调节机制,形成一类具有参数带宽化和能量归一化特性的自适应抗扰控制方法。该方法弥补了高阶控制器的相位滞后,提高了扰动抑制性能。通过仿真研究验证了所提方法在RSTP控制中的有效性和优越性。In this paper,an active disturbance rejection control scheme and design method are proposed for reheated steam temperature processes(RSTP)with high-order and large inertia characteristics realizes disturbance rejection control in RSTP under different loads.Firstly,based on the operation mechanism and control structure of RSTP,the uncertainties and relative gain changes caused by load variations are analyzed.Then,in the active disturbance rejection control(ADRC)framework,the adaptive tuning for control gain is designed to form a class of adaptive disturbance rejection control method with parametric bandwidth and energy normalization.This method provides phase compensation for the high order controller and improves the disturbance rejection performance.Finally,the effectiveness and superiority of the proposed method were verified through simulation research on the control of RSTP.
