| 摘 要： | 针对冲击地压会对巷道超前支护装备产生冲击等不利影响，提出一种基于改进型扰动观测器的控制方法。该方法在常规扰动观测器基础上，增加两个控制器，对理想模型控制器的输出进行动态补偿。使控制器不仅能够对频率较低的外界扰动进行抑制，同时能够对高频的测量噪声干扰进行消除。对其进行数值仿真与模拟实验，结果表明改进后控制方法能够有效降低冲击地压对超前支护装备产生的不利影响。

| Abstract: | A control method based on improved disturbance observer was proposed aiming at the adverse effects of impact on advanced supporting equipment of roadway by rock burst. The method increases two controller on the basis of the conventional disturbance observer to compensate dynamically for the output of ideal model controller. This control method can not only restrain the outside disturbance with lower frequency, but also eliminate the measurement noise disturbance with higher frequency. Numerical simulations and simulated experiments showed that the improved control method can effectively reduce the adverse effects on advanced supporting equipment of roadway by rock burst. |
