摘要
针对电厂锅炉主汽温度对象大延迟、大惯性、多种扰动以及非线性、时变性的控制难点,提出带有跟踪微分器的无模型自适应控制器串级系统主控制器设计方法,控制器融合衰减因子与滤波抑制测量扰动,自抗扰观测抑制负载扰动。仿真结果表明控制方法具有较强的鲁棒性和自适应能力。
Aiming at the problem of nonlinear and time-variance of boiler main stream temperature parameters,which is consid- ered long time-delay and large inertia as well a variety of disturbances,this paper proposes model free adaptive control （MFAC） strategy with tracking differentiator as main controller of serial system,which integrates delay factor into filter for suppressing measure disturbance as well disturbance observer for load disturbance.Simulation results show that this ap- proach has strong robustness and self-adaptive ability.
