On the base of model, considering the disturbance from the other 5 legs and variating load, we design an h - inf controller integrated with ip controller, which makes the system with the advantage of both h - inf control and ip control, and restrains the bad effect from variating disturbance. the simulation shows that this stradgy enhances the system robustness. in another solution, the coupling and load disturbances are regarded as the parameter variations of motor model, and the variation is observed, thus, the coupled dynamics of vamt is decoupled to 6 single motor systems
在建立了模型的基礎上,本文針對單滑塊控制系統要受到其它滑塊及負載擾動的影響,採用h _控制方法設計的h _控制器與傳統ip位置控制器結合,使得系統具有ip位置控制器和h _控制的雙重優勢,有效地抑制了變化擾動對位置輸出的影響,模擬結果表明該方法大大提高了系統的魯棒性;本文提出的另一種方案是將桿間的耦合作用和負載擾動看作電機參數變化,利用觀測器進行觀測,從而將耦合的機床動力學系統解耦成為6個獨立的電機動力學系統。In this dissertation, the development survey, research actualities and application prospect of vamt are introduced at first, and the models of kinematics, dynamics and linear motor servo are analyzed then. currently the dynamics model is complex or established mechanically, which restricts the study of control theories. thus this dissertation present a simple and easy - realized control idea, namely, the fore and torque of every leg determined by the inverse - solution of mechanics are regarded as changeable load force ( disturbance ) applied in motor, the elongation of the leg or displacement of sliding is regarded as the output of linear servo system
本文首先介紹了虛擬軸機床的發展概況、研究現狀和應用前景,然後對其運動學、動力學、直線伺服系統模型進行分析,針對目前動力學模型過于復雜或完全從機構學角度建立不便於控制的問題,提出了簡單、易於實現的控制思想,即將虛擬軸機床的動力學方程反解所確定的各桿受力(矩)視為電機的可變負載力,以桿長伸縮量或滑塊位移為伺服系統輸出,從此構成位置閉壞,實現軌跡跟蹤控制。Especially for the longitudinal heat checking of tool joint, the hoop toughness criterion of tool joint material was put forward to prevent the heat checking. based on analysis for field failure cases, minimal hoop impact work by means of mechanical calculation has been obtained, which can be used to modify the relevant contents of api rp7g
