摘要
本文针对舰载无源/光电干扰系统对抗反舰导弹的问题,阐述了大中型舰艇光电干扰伺服控制表统的组成结构、工作原理及应用前景。
     舰载光电干扰伺服控制系统采用机电式稳定平台结构。转台驱动系统采用电机扩大机——直流电动机系统。伺服系统控制方案采用闭环系统来实现。同时为实现1.8秒调舷90°的响应,并调舷定位在精确方位上(误差在±20°之内),伺服系统以线性——非线性系统来实现。即在大角度失调的情况下,伺服系统是一个非线性系统;而在小角度情况下为一个线性系统,保证伺服系统的稳定性。
     文中重点分析了伺服系统的控制技术和控制算法,详细介绍了稳定平台计算机控制系统的软、硬件设计以及设计计算。最后给出控制系统的计算机仿真结果和系统的可靠性设计。其特点是:快速反应、高精度定位和稳定性高。
Aiming at the problem that the system of passive interference and photoelectricity counterdevice antagonizes the missile of resisting naval vessel, the paper expatiates main structure, work principle and used foreground speediness reaction capability of servocontrol system of photoelectricity interference applied to capital ship and medium-sized ship.
    The servocontrol system of photoelectricity interference applied to capital ship and medium-sized ship adopts mechanical-electronic flat structure. Whirlabout flat drive system adopts direct current electromotor and servo system is closed loop. The system carries out the response of adjusting shipboard 90?within 1.8 seconds and orientates accurate position simultaneously ( the error is within ??). Servo system adopts linear and non-linear system. Namely servo system is non-linear system under the condition of large-angle maladjustment, and linear system under the condition of small-angle maladjustment, thereby guaranteeing the system's stability.
    In this paper, it analyses chiefly control technology and control arithmetic of servo system, and introduces detailedly software design, hardware design and parameter calculate. Debugging results of the computer control system and reliability design of the system are provided ultimately. The system's features are speediness reaction, high precision orientation and high stability.
