【摘要】 为提高我军某机电装备现代化水平、解决装备维修困难的问题、实现对战斗单元的远程指挥与控制，需要对其随动系统进行改造。 改造分两个阶段进行。第一阶段对随动系统核心部件电子管放大器进行模拟集成化改造。改造的目标是在保持原有放大器功能和接口不变的情况下提高其性能：改造的方法是采用工程频率法对系统内双闭环(速度环、加速度环)进行改造。前向通道在实现其原有功能的情况下，对每个模块采用不同策略进行重新设计：速度环、加速度环分别采用并联比例微分(PD)反馈和并联比例(P)反馈的控制方法进行设计，P可调。在现场调试中解决了新老放大器的通用性问题，并通过调整速度闭环内外的放大倍数、微分时间常数、反馈大小使系统达到各项要求。经过可靠性与可维修性分析、各项试验的验证和部队使用，新放大器达到和超过了各项性能指标的要求，即将通过鉴定并装备部队使用。 第二阶段对随动系统提出全数字化改造方案。目标是保持系统主体结构不变，采用模块化数字集成电路进行设计。外接网络接口，利于远程指挥和控制。应用新的控制算法，系统稳定性、快速性、准确性、可靠性都将有较大提高，为今后其它随动系统的改造提供参考。更多还原

【Abstract】 For settling the problem of the army equipments’ maintaining, improving the equipments’capability, controlling and directing the equipments from long distance through the network, we must alternate their servo systems.In the first stage, we changed the Vacuum Tube Amplifier with Analog 1C, that is the core of servo system .For retaining the function and outside junction, useing Engineer Frequency Method alternate the system’s inner two closed loop (velocity loop and acceleration loop). In the Amplifier’s forward channel, using different strategy redesign each blocks. Velocity loop use Parallel Proportion And Differential Feedback, and acceleration loop use Proportion Feedback. Each proportion can be adjusted. In locale debugging, we settle the problems of the compatibility between new and old. And by adjusting proportion, differential time constant and each block’s magnify multiple, system achieve the request. All experiments, security and servicing analysis, troops’ testify prove that the new Amplifier attains and exceed all the guidelines. And experts will check the item soon.In the second stage, we will alternate the servo with modularization numeric 1C, but retain the main configuration. The system has network. After alteration, the system will be more stable, more veracious, swifter and more reliable.更多还原
