目前,由于被测目标的运动速度越来越快,所以对光电跟踪系统的捕获性能要求也越来越高,而改善光电跟踪系统的动态性能是提高对光电跟踪系统快速捕获性能的重要途径。IATE最优控制对位置阶跃信号具有响应快速、超调小和稳态误差小等优点。为此,本文尝试将IATE最优控制应用到光电跟踪伺服系统中,以期达到优化光电跟踪伺服系统动态性能的目的。最后,本文针对特定的光电跟踪架进行了IATE最优控制系统设计并进行了大量的仿真和实验测试,实验结果和仿真结果相吻合,达到了预期目的,同时也表明了IATE最优控制在所能跟踪的信号的范围内线性度好,降低了超调量,缩短了调节时间,抑制了抖动,方法简单,易于实现,具有重要的工程应用价值。

at present, the target′s movement speed is faster and faster, so the requirements on the capturing of optical tracking system is higher and higher, while ameliorating the dynamic performance of photoelectric tracking system is an important approach to improve transit rapid acquisition.IATE optimal control on posi-tion step signal with advantages of rapid response, small overshoot and small error of steady state.To this end, this paper attempted to apply IATE optimal control to optoelectronic tracking servo system, to achieve the goal of optimization of optoelectronic tracking servo system dynamic performance.Finally, based on the specially appointed photoelectric tracking IATE optimal control system, designed and tested a lot of simulations and experiments, the experimental results tallied the simulation results, shows good linearity of the IATE opti-mal control within the signal scope it can track, and reduce the overshoot, shorten the adjusting time, suppress the jitter.The method is simple, easy to implement, has important value of engineering application.
