Introduction to an integrated design for motion systems using over-actuation

摘要

In this paper an introduction and motivation is given towards an integrated design approach for motion systems using overactuation. Looking to motion systems and their history, the current status of mechatronic motion systems is discussed. One of the main aspects that limit performance in mechanical systems is the presence of vibrations. An overview is presented of several passive and active methods to solve vibration problems. Active vibration control can be regarded as a form of overactuation to improve system performance. It is expected that an integrated overactuated design approach will be advantageous over traditional vibration control solutions, which often make use of adaptations after the mechanical design has been completed. Before a framework for an integrated design approach can be posed, different strategies of overactuation must be investigated. To study the closed-loop characteristics of resonances in mechanical systems with more actuators more closely, some first explorations of a dual-input single-output motion system are made.
