The control of flexible systems is a large and important field of study. Unwanted transient
deflection and residual vibration are detrimental to many systems ranging from nano …

摘要对于步进扫描投影光刻机, 掩模台和工件台的同步伺服性能将直接影响整机技术指标.
掩模台和工件台是典型的六自由度超精密运动台, 在耦合动力学, 复杂内外部干扰条件下兼顾高 …

An underactuated tower crane exhibits a significant payload sway especially under three
simultaneous motions involving trolley displacement, jib rotation and payload hoisting. This …

Input shaping reduces residual vibration by generating a command signal that is self
canceling. That is, any vibration caused by a portion of the command is canceled by a later …

Input shaping reduces residual vibration in computer controlled machines by convolving a
sequence of impulses with a desired system command. The resulting shaped input is then …

Precise position control and rapid rest-to-rest motion is the desired objective in a variety of
applications. The desire for reducing the maneuver time requires reducing the inertia of the …

The feedforward compensation of nonlinearities, ie, hysteresis and creep, and unwanted
vibrations in micromanipulators is presented in this paper. The aim is to improve the general …

The problem of flexible spacecraft attitude tracking control with guaranteeing the prescribed
performance is investigated. First, the Lagrangian model of the flexible spacecraft is derived …

This paper presents an investigation into development of feed-forward control strategies for
vibration control of a flexible robot manipulator using command shaping techniques based …

This paper presents an optimal performance control scheme for control of a three
dimensional (3D) crane system including a Zero Vibration shaper which considers two …
