摘要
由于最小节拍组合控制系统对位置阶跃信号响应快、超调小、稳态误差小,有利于光电跟踪系统快速捕获目标,本文针对特定的光电跟踪架设计了最小节拍组合控制系统,并对其进行了仿真测试和实验测试。实验显示,仿真结果和实验结果基本吻合,不仅表明最小节拍组合控制系统在所能跟踪的信号范围内线性度好,还验证了校正环节和前置滤波器所起的作用。提出的方法降低了超调量,减少了调节时间,抑制了系统的抖动,体现了最小节拍组合控制系统的特点。这种最小节拍组合控制系统在数引方式下能快速捕获和锁定目标,具有重要工程应用价值。
Abstract
As the minimal prototype control system has fast response, smaller overshoots and smaller stable errors, it is suitable for a photo-electric tracking system to capture targets. Therefore, this paper designs a minimal prototype control system for a photo-electric tracking frame and also performs simulation and experimental tests。The experiments show that the simulation results are coincident with that of experiments well, which not only demonstrates that the minimal prototype control system is a linear system in the certain region of tracking signal, but also indicates the influences of a correction part and a front filter. This control method reduces overshoot and adjusting time, inhibits the jitter effect of system. These all show that minimal prototype control method can be used to acquire fast targets in digital guiding and is valuable in the project application for opto-electronic tracking systems.
