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

飛行器軌道機動過程中，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軌道參數.本文所述演算法是該工程問題的探討和解決方案.文章建立了軌道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耗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耗量的最小方差估計;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能快速、準確地估計推進發動機的質量秒耗量和向機動目標施加的實際推力

Usually we linearize them approximately in industrial process, but in some cases this ca n ' t satisfy the request of automatic control which makes us consider the nonlinear factors in the industrial process. in practical process of power plants the typical structure nonlinear case is dead - zone and the latter case is the nonlinear variance of objects ' parametres with the changes of working condition. the nonlinear research is parallel with the linearity and adaptive method can be used to deal with nonlinear cases. in this paper two adaptive control methods are used to solve the problems brought by the dead - zone of boiler negative pressure system and the nonlinear changes of the milling system ' s character parameters, which achieved good results

在生產中通常對非線性作近似線性化處理；但在某些情況下線性近似達不到自動控制的要求，必須對生產過程中的非線性情況進行考慮。在火電廠的實際生產中，典型的結構非線性之一是死區；參數非線性多發生在控制對象特性隨工況變化而變化，表徵其特徵參數變化呈非線性。非線性控制的研究與線性控制的研究是并行的，針對非線性情況，可以採用自適應的控制方法。
