碩士 === 清雲科技大學 === 機械工程研究所 === 94 === The multi-axis platform is a common mechanism in the servo mechanisms. Friction is an inevitable physical phenomenon present in mechanisms which produces undesirable behaviors in control systems such as position and tracking errors, and limit cycles. It also involves static, viscous, coulomb friction etc. The effects of system with friction are considered by the multi-axis platform. Then we develop a general estimation method for the identification of equivalent inertia and damping of systems with friction. Furthermore, the first and second order characteristics are going to be considered to estimate the parameters respectively by the experiment.
