  1. An on - line minimum - variance estimator was developed for thrust acceleration applied to orbit transfer using discrete - time radar measurements. the mass - flow - rate of propellant was selected as a state variant, which was estimated by employing an integral state model and ekf filter. the variation equations for measurement vector to mass - flow - rate have been established to linearize the discrete - time measurement equations. the algorithm has applied successfully to maneuver process in commanding satellite into geo - stationary orbit. the results show that the algorithm developed here can monitor and determine whether engine works well or failure precisely and quickly during orbit transfer process

    飛行器機動過程中,為跟蹤、定位機動目標和干預機動控制過程,需要統計處理離散的雷達觀測量實時估計推進發動機的推力,進而確定飛行器的瞬時參數.本文所述演算法是該工程問題的探討和解決方案.文章建立了機動過程中連續變質量運動模型和離散雷達量測模型,推進發動機的質量秒量作為表徵推力加速度的一個近似常量,應用擴展卡爾曼濾波對離散的雷達測量數據進行順序統計處理給出秒量的方差估計;文章詳細地推導了線性化量測模型的變分方程和觀測矩陣;模擬結果表明該演算法快速、準確地估計推進發動機的質量秒量和向機動目標施加的實際推力
  2. Within a given time a train travels from one station to the next along level track or non - zero gradient track, it is desirable to find a feasible control strategy that minimizes fuel consumption
