本論文針對使用四個Mecanum輪之全向機器人,由全向輪的滾動、滑動限制條件,推導其運動學模式,再利用 Lagrange方程式推導其動力學模式。考慮系統不確定項,使用反向步進(backstepping)法,依Lyapunov穩定理論推導非線性穩定適應控制律,引入非線性阻尼項及參數估測器,以補償系統之不確定性和近似誤差所造成的影響。最後,為瞭解所設計之控制策略性能,使用三階軟楔內插法規劃機器人運動之期望軌跡,再以Matlab程式模擬驗證所提控制律,確能讓機器人達到對隨意軌跡追蹤控制之目的。

In this thesis, an omni-directional wheeled robot with four Mecanum wheels is considered. Based on the rolling and sliding constraints of the omni-directional wheels, the kinematics model of the robot is first derived, and then its complete dynamics model is derived using Lagrange's equations. Considering the mass and friction uncertainty, the backstepping method is used to derive a nonlinear stable adaptive control law based on Lyapunov stability theory. In order to compensate for the model uncertainty, a nonlinear damping term is included in the control law, and the parameters update law with -modification is considered for the uncertainty estimation. Finally, computer simulations are used to investigate the control performances using desired trajectories obtained by the cubic spline interpolation.
