doi:10.3969/j.issn.1000-1093.2018.02.026

Abstract

Abstract: The traditional charging process of warhead is finished by hand, and the charging efficiency is low and the charging quality is not guaranteed. An automatic charging device for warhead is proposed. The structure of charging device is designed, and for the jitter problem of automatic charging device, a dynamics model is established based on rigid-flexible coupling. Through the comparison of acceleration control algorithm and S curve algorithm, it is found that the jitter of charging device is the weakest when using the S curve algorithm. The S curve algorithm is optimized to five segments and is implemented on the controller by interpolation fitting. In physical testing, the S curve algorithm can be used to avoid jitter obviously. The results show that the optimized algorithm has better control performance. The S curve algorithm is optimized and applied to reduce the jitter of the device. Key

Key words: warhead, automaticchargingdevice, rigid-flexiblecoupling, accelerationcontrolalgorithm
