  1. A general stack equation of mobile robot based on analyzing the motion of planar motion object and the mathematical models of four different kinds of common wheels is developed, accordingly, the mobility of mobile robot is addressed and the forward and inverse solutions to speed for specific configuration driven by differential speed are derived. utilizing the muir and newman convention, the description of the posture transformation matrices between different coordinate frames and the solution for the speed of point located on these frames are introduced. according to posture estimation, a more accurate method, dead reckoning algorithm, is developed for a specified configuration characterized by differential speed motorization, and simulations of this algorithm and other traditional methods are carried out using matlab while traversing a circular path

    本文對兩輪差速驅器人的運學及其本體緩沖設計進行了探討,在對平面運物體運分析的基礎上結合四種常用車輪的數學模型,推導出了一個通用的移器人堆積方程,在此基礎上分析了移器人的移能力、並針對兩輪差速構型推導了速度正解與逆解;使用muir和newman的運學建模方法,推導了移器人上點及連桿坐標系位姿、速度變換關系矩陣及求解方法;在移器人位姿識別方法中結合差速驅構型對位推演算法進行了分析:推導了一種理論精度較高的位推算演算法,並使用matlab對其與傳統的推算演算法在跟蹤圓弧軌情況下進行了模擬;最後針對本文所研究的器人給出了一種比較系統、可靠的緩沖結構設計思路,較好地解決了移器人作業過程中外界因素及本身設計中引入的各種不確定誤差問題;本論文研究成果已在本實驗室所開的樣上得到實現,經過應用與考核證明其中的分析與設計是切實可行的。
  2.

    首先,建立帶偏的直升點質量模型,然後對狀態變量和控制變量進行無量綱處理,因為狀態變量和控制變量量值相差較大,這使得優化演算法收斂效果變差,所以需要選擇適當的縮放因子,最後把直升單臺停車后的飛行軌表示成一個最優控制問題,即在考慮直升性能限制和far規范后,指定一個優化性能指標,選擇合適的路徑約束,然後再解最優控制問題。
