【摘要】：采用传统的单Bang-Bang控制的光电设备进行精定位时,系统放大倍数为无穷大,所以系统不易稳定。本文分析了单Bang-Bang控制的不足,提出了一种变结构最优控制方法。该方法在粗跟踪时用Bang-Bang控制,在进入小偏差范围内切换为线性控制。在线性控制时,根据不同调节器的的不同特点,提出了红外一阶捕获,红外二阶跟踪的策略,并同时给出了Bang-Bang控制和线性控制的切换准则,红外一阶捕获和红外二阶跟踪的切换准则。实验显示,采用提出的方法光电设备的90°双目标定位能力在2.3s左右,比传统方法缩短了近1s,快速性大大提高。另外,利用激光测距机可以给出舷角相差90°的双目标三维信息数据率为0.45Hz,提高了双目标时系统的光电对抗能力。
[Abstract]:When the traditional optoelectronic equipment controlled by single Bang-Bang is used for precise positioning, the magnification of the system is infinite, so the system is not easy to be stabilized. In this paper, the shortcomings of single Bang-Bang control are analyzed, and a variable structure optimal control method is proposed. The method is controlled by Bang-Bang in coarse tracking, and switched to linear control in the range of small deviation. In the case of linear control, according to the different characteristics of different regulators, the strategy of infrared first-order acquisition and infrared second-order tracking is proposed, and the switching criteria of Bang-Bang control and linear control are also given. Switching criteria for infrared first order acquisition and infrared second order tracking. The experimental results show that the proposed method can locate 90 掳double targets in about 2.3 s, which is about 1 s shorter than the traditional method, and the rapidity is greatly improved. In addition, by using laser rangefinder, the three-dimension information data rate of two targets with 90 掳deviation of side angle can be given to 0.45 Hz, which improves the photoelectric countermeasure ability of the system with two targets.
