| Abstract: | In the research field of flexible robot arms, it is an important problem in the implementation of control that how to smooth the flexible vibration quickly in the mean time of fixing position of target. This paper first studies the theory of measuring speed feed back control to smooth the vibration, discussing the influence of this method on the stability and dissipation of system, and then approaches the implementation of the theory in a flexible dual link flexible robot arms. At last a method called measuring speed bridge which is easily realized in engineering is provided. The results indicate that this simple economical reliable method can restrain the flexible vibration effectively. It has high application values and can be used widely in the field of space robot. |
