    摘要:

    针对标准自抗扰控制器在热力系统高阶大惯性过程控制中效果不佳的问题,提出一种基于高阶系统模型信息的补偿型自抗扰控制器设计方法。基于理论分析和各可调参数的物理意义,给出了其定量化参数整定方法并从观测误差、开环频率特性和参数稳定域等方面分析了补偿型自抗扰控制器能够提高控制效果的原因。仿真对比分析表明,该方法在设定值跟踪、抗扰能力和性能鲁棒性上均有较好的改进效果,方法能显著改善对高阶大惯性过程的控制效果,具有很好的工程推广潜力。

    Abstract:

    Aiming at the problem of poor control effect of standard ADRC for thermal system with high order and large inertia characteristics, a design method of compensation ADRC based on high order system model is proposed.SBased on the theoretical analysis, the quantitative parameter tuning method and the physical significance of each parameter are given, and the reason why the extended state observer can improve the control effect compared with the standard ADRC controller is analyzed from the perspective of observation error, open-loop frequency characteristic and stable region. The simulation results show that the proposed method has a good improvement effect on set point tracking, disturbance rejection ability and performance robustness. The proposed method can significantly improve the control effect of large inertia process, and has a good engineering promotion potential.
