Abstract

In this study, control design of injection velocity in injection molding processes is presented. Because the aim of injection velocity control is to follow velocity profile which is designed to maintain a uniform melt-front speed during filling phase, the injection velocity profile is firstly defined. Proposed control, fuzzy sliding mode control, is then employed to follow velocity set point as close as possible. To compare the effectiveness of proposed control, the result will be compared to sliding mode control and set point. Injection velocity response showed that proposed control can follow velocity set point with small error and also decrease chattering due to sliding mode process.
