Abstract
The injection velocity dynamics are found to be both time-varying and non-linear and therefore difficult to control using a conventional fixed parameter controller. In this work, an adaptive injection velocity control system with some special features such as anti-estimation windup, adaptive feed-forward, profile shifting and cycle-to-cycle adaptation is designed, implemented, and experimentally tested. The developed system is demonstrated to have excellent control performance with very good robustness for a wide range of operating conditions.Keywords
