某位标器抗扰控制技术研究

对某位标器抗扰控制技术进行了研究。建立了位标器随动系统模型，针对比例积分微分（PID）控制的局限性，引入微分跟踪器构造微分环节，用系统观测器重构补偿扰动影响，以改善系统的控制效果。仿真结果表明：加入微分跟踪器和观测器的系统有较好的抑制干扰能力，系统鲁棒性提高，削弱了扰动对系统性能的影响。

Research on Technology of Anti-Interference Control for a Coordinator

The technlogy of anti-interference control for a coordinator was studied in this paper. The model of follow-up system was estabilshed. Aimed to the limitation of PID control, the tracking differentiator was introduced to construct the differential part, and the system observer was used to compensate the effect of disturbance, which would improve the system control. The simulation results showed that the modified system had a better capability and anti-interference ability, which the system robustness was improved and the effect of interference on the system performance was weaken.
