This paper proposes a new design concept that takes into consideration the construction of a mechanism that consists of a structural system and a control system. In order to obtain a fine mechanism with high performance, it is necessary to prepare the structural system with higher controllability in the design stage. The essence of the concept is to make practical lse of the nodes at the vibration modes of the structural system for the purpose of suitably arranging the controller and the sensor within it. Firstly, uncontrollability and unobservability, which correspond to the pole-zero cancellation, is realized on the vibration node. Next, it is shown that the controller located on the vibration node cancels any undesirable resonance peak of the structural system required for achieving higher controllability. The effectiveness of the design concept is demonstrated by the design of the optical servosystem.
