白沙导弹靶场(WSMR)七种可移动式遥测采集系统(TTAS)作为主要遥测跟踪系统服务于WSMR已二十年之久。对原有模拟位置控制系统(天线锁源、伺服功率放大器、位置补偿)增加的维修费用与跟踪系统性能明显改善的潜力有关,但现代技术提供的自诊断能力导致了WSMR开展新设备研制工作,其目标是研制一种新的几乎是全数字的跟踪系统样机,来取代TTAS中老的模拟控制系统。一种现代的圆锥扫描馈源取代了原有的单脉冲馈源,脉宽调制功率放大器取代了原来使用的可控硅整流器,基于VME总线,使用实时操作系统的计算机取代了模拟补偿和系统的全部控制。文中,在概述跟踪系统样机之后,采用根轨迹、计算机仿真,而且从实际跟踪系统出发,采用为计算机控制器开发的伺服测试软件来描述为跟踪系统样机而开发的新位置控制算法结果。为了比较,介绍了用计算机仿真研究老式模拟系统的结果。也介绍了TTAS中遇到的直接影响位置控制的一些问题。为适应所有临界跟踪系统的非线性(功放饱和、电流限制、死区和控制输出饱和),所有跟踪状态(自动跟踪、手动、使用外部的引导数据),不同的操作带宽和系统所有可能的驱功输入而设计了新的位置控制算法。它使控制系统从1型变成了2型,改善了TTAS的动态能力。
The White Sands Missile Range (WSMR) Seven portable telemetry acquisition systems (TTAS) serve WSMR for two decades as the primary telemetry tracking system. The increased maintenance costs of the original analog position control system (antenna lock source, servo amplifier, position compensation) are related to the potential for significant improvements in tracking system performance, but the self-diagnostic capabilities provided by modern technology have led WSMR to develop new equipment, The goal is to develop a new almost all-digital tracking system prototype to replace the older analog control system in TTAS. A modern conical scanning feed replaces the original single-pulse feed, a pulse-width modulated power amplifier replaces the silicon controlled rectifier originally used, and replaces the analog compensation and system based on the VME bus with a real-time operating system computer Full control. In this paper, the root locus and computer simulation are introduced after the tracking system prototype is summarized. And based on the actual tracking system, the servo control software developed for the computer controller is used to describe the result of the new position control algorithm developed for tracking the system prototype. For the sake of comparison, the results of computer simulations on older simulation systems are introduced. Some problems encountered in TTAS that directly affect position control are also covered. To accommodate all criticality tracking system nonlinearities (power amplifier saturation, current limit, dead zone and control output saturation), all tracking states (auto-tracking, manual, using external boot data), different operating bandwidths and all possible system drives Power input and design a new position control algorithm. It changes the control system from Type 1 to Type 2, improving the dynamic capabilities of TTAS.
