Summary: | 碩士 === 國立中興大學 === 機械工程學系 === 93 === In this thesis, a new stable adaptive controller with friction observer for six-DOF Stewart platforms is proposed. By considering a nonlinear friction observer to compensate for the effects of friction and a nonlinear damping for model uncertainty, a proper Lyapunov function candidate is selected. Then a stable adaptive controller, with parameters adaptation law with modification, is derived using Lyapunov stability theory. Computer simulations and implementation studies using a dSPACE DS1103 single-board controller are presented to illustrate the effectiveness of the suggested control strategy.
