为了解决控制系统中的时滞和噪声问题，在这项研究中，我们集成了一个扩展的状态滤波器的信号滤波到自抗扰控制（ADRC）系统，并推导出一种改进的ADRC方法。该方法除具有自抗扰控制器的主动抗扰和主动跟踪估计功能外，还具有主动滤波和主动超前预报功能，能够滤除量测噪声对系统状态观测的影响，同时减小系统控制输出与传感器输入检测之间的延迟。我们通过在仿真环境中的评估，所提出的方法可以预期实现提高控制精度和增加闭环控制系统的稳定性验证。
To address time delay and noise problems in control systems, in this study, we integrated an extended state filter for signal filtering into an active disturbance rejection control (ADRC) system and derived an improved ADRC approach. In addition to the active anti-disturbance and active tracking estimation functions of the existing ADRC, the proposed approach also includes active filtering and active advance prediction functions, which can filter out the effect of measurement noise on system state observation while reducing the delay between the system control output and the detection of the sensor input. We verified through an evaluation in a simulation environment that the proposed approach may be expected to achieve improved control accuracy and increase the stability of closed-loop control systems.
