Abstract

High levels of vibration affect the performance limit of machines, such as speed and efficiency. Vibration suppression is very important for the application of motion control system in high-end equipment. The performance of many complex and precise mechanical systems can be improved by using command shaping techniques to suppress machine vibration. The input shaping technique, originated in MIT artificial intelligence laboratory, has proven to be highly effective and strongly robustness for flexible mechanical systems. This paper studied and derived the mathematical expression of the input shaper, listed and compared the characteristics and robustness of several main shapers, and simulated the vibration suppression effect of Extra insensitive shaper. And then, the vibration suppression effect of four kinds of shaper was verified carefully by experiments of a platform consisted of two axes linear motors. Appropriate comparison and discussion were carried out for the results. The conclusion had reference significance for practical engineering of motion control.
