And then, the error matrixes of location and kinemics of the end point, and the on - line error compensation method are given based on robot ' s dynamics. finally based on puma robot, three simulation examples are given respectively ; the first is about the location error and on - line location error compensation, the second is about the kinetic error and on - line kinetic error compensation, the third is about location and kinetic errors causing by robot ' s dynamics and the on - line error compensations. the simulation results show that : a ) location error of the end point based on elastic deformation of the sensor will be about millimeter ' s degree under the permitting load, b ) the on - line error compensation methods given are available
第三章首先概括了目前機器人連桿慣性參數識別的四種方法,總結這些方法的優、缺點;指出這些方法存在的問題是:或者需將機器人解體,不能在線進行參數識別,或者不能給出機器人連桿獨立的慣性參數值,只能獲得慣性參數的組合值,而這些方法的共同問題是:不能考慮機器人連桿的關節特性;本章提出了一種基於腕力傳感器的機器人末端連桿慣性參數在線識別方法,給出了該方法的理論計算和推導;研究提出了以腕力傳感器輸出為前提的、基於newton - euler動力學的機器人動力學正向、逆向遞推公式;針對機器人負載參數辨識必須在線、實時的特點提出了基於腕力傳感器的負載參數在線識別方法,給出了負載參數識別的步驟。A new robust adaptive scheme which are used for tracking of this robot with parametric and bounded external uncertainties is proposed in this thesis. the controller is consist of a controller which is proposed by slotine1 ' 1 and nonlinear continued feedback compensation part. by estimating the unknown physical parameters of robot on - line, it can eliminate the effects result by parameters and external disturbances and guarantee gas and uniform boundedness of parametric estimation. the only information required in setting up the strategy is the output states of jionts, while the inversion of the inertia matrix or estimation the bound of the inertia matrix and measure the jionts accelerations are not needed. it is shown by simulations that the proposed control scheme has quicker convergence velocity and better control precision than paper [ 1 ] and control schemes at present
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。
