摘要:
快速反射镜(Fast Steering Mirror,FSM)是光电跟踪系统中精跟踪的重要组成部件,FSM系统需要满足响应时间快,高精度以及抗干扰等性能要求。提高跟踪精度以及减小响应时间是快反镜系统需要解决的关键问题。本文提出了一种改进非线性状态误差反馈控制律的自抗扰控制器,在传统自抗扰优良控制效果的基础上,进一步改善了系统的动态性能和稳态性能。经过大量仿真研究,与传统自抗扰控制相比,该方法使系统的动态性能提升80%左右,跟踪精度增加了46%左右。
Abstract:
The fast steering mirror (FSM) is acritical component in optoelectronic tracking systems used for fine tracking. An FSM system must meet the performance requirements of fast response time, high precision, and anti-interference. Improving the tracking accuracy and reducing the response time are the main objectives of an FSM system. In this study, an active disturbance rejection controller (ADRC), which improves nonlinear state error feedback, is designed. In addition, the dynamic performance and steady state performance of the system are further improved based on the excellent performance of the traditional ADRC. After many simulations, the dynamic performance and tracking accuracy of the system were improved by approximately 80% and 46%, respectively, as compared with the traditional ADRC method.
