針對該模型具有參數及有界外部擾動不確定性時提出了一種新的魯棒自適應控制策略，控制器由基於slotine的控制器和非線性連續反饋補償控制器構成。通過在線估計機器人的未知物理參數，有效的消除了由參數及外部擾動所引起的不確定性影響，保證系統達到漸近穩定和參數估計一致有界。與現存的許多控制方法相比，該控制策略不需求解慣性矩陣的逆或估計慣性矩陣的界，不需測量關節加速度，而唯一需要了解的只是系統輸出的位置及速度狀態。Picture that put forward in the article graph and data structure reciprocal mapping support not merely to map graph from data structure efficiently, besides, regard graphics element as a unit, analyze and discern to user ' s modified graph, produce the corresponding data structure automatically, maintain consistency of graph and data structure efficiently on the foundation of expanding case graphic tools effectively, we direct against the intrinsic characteristic of traditional waterfall model, proposesmall loop model to software analysis based on graph and data structure reciprocal mapping solve problems of slow information feedbackand high track back cost efficiently
文中提出的圖數互逆映射的思想，不僅對數據結構到圖形映射進行高效率地支持，同時，以圖形元素為單位，對用戶修改後的圖形進行分析和識別，自動生成相應的數據結構，有效地維護了圖數一致性。在對case圖形化工具進行有效擴展的基礎上，我們針對傳統瀑布開發模型的固有特點，提出了基於圖數互逆映射的軟體分析小循環模型，有效解決了傳統軟體分析設計階段信息反饋慢、回溯代價高等問題。Feedback is used in control, but it is just limited to adaptive process. adaptive inverse control dominates alterable parameters rather than signal flow in system not so as conventional control
和傳統的控制不一樣，自適應逆控制採用反饋不是為了控制系統中的信號流動，而是用於控制系統中的可變參數。For this reason, the paper is aimed at the electro - hydraulic servo - system nonlinear problem, and proposes the feedback linearity means ( that is the inverse system method ) against the system mode systematically to transform such nonlinearity into the pseudo linear system. the system mode not merely continues to have system message completely feedback the linearity means, but also achieves the great limit linearization of controlled device, for designing the controller to advance system dynamic characteristic and performance index and supply the ideal terrace in the interest of the application linearity control theory
為此，本文針對該非線性問題，提出了逆系統狀態反饋線性化方法，將其非線性系統轉化成偽線性系統，不僅完全保留了系統的信息，而且還實現了被控對象的大范圍線性化，為應用線性控制理論去設計控制器為提高系統的動態特性和性能指標提供了理想的平臺。Concretely, adaptive inverse control is an open loop control toward dynamic characteristic of system by acting inverse of plant transfer function as series controller, so it avoids instability as a result of feedback. at the same time, because the control of dynamic characteristic of system and plant disturbance is to be treated separately and that has not influence mutually
具體地說，自適應逆控制是用被控對象傳遞函數的逆作為串聯控制器來對系統的動態特性作開環控制，從而避免了因反饋而可能引起的不穩定問題；同時又能做到對系統動態特性的控制與對象擾動的控制分開處理而互不影響。This paper presents a kind of nonlinear adaptive inverse control with - filtered algorithm, which has adaptive disturbance canceler and feedback compensation in it
