  1. To overcome this problem, the author researching from the core of active disturbance rejection control theory " fal function ", having the advantage of : small errors, large gains ; big error, the small gains character, designs a nonlinear pid gesture controller. simulation results showed that the design of nonlinear pid controller shortening the small satellite gesture catch time and improving the attitude control precision

    為了克服這個問題,本文從自抗擾控制理論中的核心「 fal函數」出發,基於fal ( e , , )函數具有:小誤差,大增益;大誤差,小增益的特性,設計了一種非線性pid姿態控制器,比較好的縮短了小衛星姿態捕獲時間,一定程度上提高了姿態控制的精度。
  2. The new adrc technique was concluded from the related references in recent years, and the adrc theory was systemically introduced, which included tracking - differentiator ( td ), extended state observer ( eso ), nonlinear pid, nonlinear feedback ( nf ) and active disturbance rejection controller ( adrc ), and etc. the author first designs a pd attitude control system, indicating : using pd attitude control, the time of small satellite gesture capture is long and the precision of control is low

    從近幾年有關文獻中總結了自抗擾控制新技術,系統介紹了自抗擾控制理論,其中包括跟蹤微分器( td ) 、擴張狀態觀測器( eso ) 、非線性pid 、非線性反饋( nf )和自抗擾控制器( adrc )等。設計了主動磁控小衛星pd姿態控制系統。指出採用pd姿態控制,微小衛星姿態捕獲時間較長,姿態控制精度較低。
  3. As the complexity of flight tasks increases, the linearized equation based on the small disturbance theory is no longer adequate for the design of control systems, and the necessity of exploring a nonlinear approach seems increasingly obvious

    隨著飛機飛行任務不斷趨向復雜化,基於小擾動線性化方程的線性系統設計方法已經難以滿足現代飛機飛控系統的設計要求。這就迫使我們研究飛機的非線性控制律的設計方法。
