The servo motion dynamics of the ship - borne rocket launcher under the condition of ship sway is studied 摘要该文研究了某舰载火箭炮在舰船摇摆情况下随动系统调炮时的火箭炮受力问题。
The thesis introduces a full digital super - low speed servo system based on micro - controller 80c196kc 介绍了以80c196kc单片机为核心的全数字超低速随动系统，分析探讨了系统的控制规律和实现方法。
Give the design of the substitution of the whole fin stabilizer control system by plc , and finish all the preparatory works 对设计完成后的随动系统进行测试，验证其是否符合减摇鳍系统的工作要求。
That is to say we need to better its precision , reliability and adaptability . because of all above we select the plc as the substitution 在这种考虑的基础上，我们选定可编程控制器对减摇鳍原有的随动系统进行替换改造。
Its control precision , reliability and adaptability are not good enough . as the electronic technology develops so fast , the fin stabilizer also needs to be improved 随着电子技术的迅猛发展，减摇鳍系统也需要不断完善和改进，而随动系统的改造就成为必然。
So the alteration and improvement of servo system is necessary . the improvement of servo system should base on the merits of the old one , and cover the shortage 随动系统改造的方向应该是在原有优点的基础上，弥补其不足，也就是提高系统的可靠性、精度以及灵活性。
The system that electrical power is supplied by silicon - controlled , speed abjusted by direct current double loop - locked and controlled by microcomputer is the high acurracy digital system following the input signal 摘要微机控制的晶闸管供电的双闭环直流数字调速系统是高精度复现输入信号的数字随动系统。
Replace the old servo system with the fpo programmable controller of matsushita electric works . improve the system on the basis of its primary functions . the performance of the system improved is analyzed 选用日本松下公司的fpo系列plc对减摇鳍的原有随动系统进行替代改造，在实现原有功能的基础上进一步完善。
But considering the influence of artillery goal mensuration , computer calculate and artillery following system , the axis of artillery pipe and goal have deviation , this error is dynamic tracking error 但由于火炮目标测定器、计算机解算、火炮随动系统等环节的影响，火炮身管的轴线与目标存在偏差，该项误差即为动态跟踪误差。
2 } according to the characters of virtual instrument , modern testing theory and systemic and all - sided analysis on the servo of aag , general hardware project of virtual instrument is confirmed 2 >根据虚拟仪器技术的特点以及现代测试理论，并在对高炮随动系统电子设备进行全面分析的基础上，确定了虚拟仪器系统的硬件总体设计方案。
